Fixes the following incorrect behaviour of fold caused by the i18n patch:
```
$ LC_ALL=en_US.UTF-8 fold -b -w6 <<< $'1234567890\nabcdefghij\n1234567890\n'
123456
7890

Fixes: 97967f71c8 ("coreutils-i18n.patch: synchronize the patch with openSUSE")
Resolves: RHE L-60295
- sync i18n patch with SUSE (Kudos to Berny Völker!)
- add some test dependencies to execute additional part of the upstream test-suite
Resolves: rhbz#2272063
New tests in tests/pr/pr-tests.pl have names which - with the suffix
"-mb" for the i18n test - become "too long (>30)". I adjusted
'tests/Coreutils.pm' accordingly.
- coreutils-i18n-suse-merge.patch:
* src/exand.c,src/unexpand.c: Avoid -Wcomment warning.
* src/cut.c (cut_characters_or_cut_bytes_no_split): Change idx from size_t
to uintmax_t type to avoid a regression on i586, armv7l and ppc.
Compare upstream, non-MB commit:
https://git.sv.gnu.org/cgit/coreutils.git/commit/?id=d1a754c8272
(cut_fields_mb): Likewise for field_idx.
* tests/misc/cut.pl: Remove downstream tweaks as upstream MB tests are
working since a while.
Patches written by Pádraig.
Note that the corresponding i18n/sort-month test was not included
because it breaks unless sort is compiled -Dlint and we do not want
to decrease performance of the resulting RPMs (and valgrind is not
installed in production buildroots anyway).
* src/uniq.c (check_file): Instead of copying the whole code, simply
determine the value of 'new_group' by invoking different_multi in
the multi-byte case.
* tests.misc/uniq.pl: For comparing the stderr message with the
expected result, all multibyte-typical ‘...’ must be replaced
by '...'. Add a ERR_SUBST expression to do that.
* src/cut.c (convfail,CONVFAIL): Change to bool to avoid a GCC
warning about signed vs. unsigned. Also avoid "set but not used"
of convfail in cut_characters_or_cut_bytes_no_split.
(cut_fields_mb): Fix indentation.
* src/expand.c: Add include for wctype.h to declare isblank().
* src/fold.c (fold_file): Add "const" attribute to 'filename' parameter
to avoid "const cast away" in call in main().
* src/join.c (xfields_multibyte): Remove unused variable 't'.
(keycmp): Evaluate the return value of wcrtomb(). Furthermore,
when copying 'beg' to 'copy' array elements, remove the unnecessary
cast to unsigned.
(main): When assigning the newline string to 'newtab', cast away the
implicit const.
* src/pr.c: Remove the unneeded include of wctype.h and the define
of iswprint().
(print_stored): Add the unsigned qualifier to 'first' and 'last' to
avoid a signedness warning.
* src/sort.c (getmonth_mb): Cast away the 'const' qualifier of 's'
when assigning to *ea.
* src/uniq.c (different_multi): Evaluate the return result of wcrtomb();
Add the include of assert.h for that.
