The FTBFS has started to happen with rpm-4.16.90-0.git15395.2.fc35.

DEBUG util.py:444: error: line 116: Unknown tag: /chroot_tmpdir/srpm_unpacked/SOURCES/macros.ruby

As the `%{?load:...}` is undocumented, it is gone.

Because setting the option makes some tests stable that are currently randomly
failing with error on especially s390x and aarch64.
We observed the failing tests are calling `assert_in_out_err` method
calling `invoke_ruby` calling method.
Then when the `th_stdout.join(timeout)` or `th_stderr.join(timeout)` returns
`nil` as thread timeout in `invoke_ruby` method, it causes the error. [1][2]
The `test_timeout_scale` macro is to set the environment variable
`RUBY_TEST_TIMEOUT_SCALE` to increase the timeout in `apply_timeout_scale`
method as <new timeout> = <timeout> * <timeout scale>.
As an example, `TestBugReporter#test_bug_reporter_add` test's
maximum thread timeout was 56+ seconds for the default timeout 10 seconds. [3]
In this case setting `RUBY_TEST_TIMEOUT_SCALE=6` (6 * 10 = 60) is good enough
for 56+ seconds.

This is needed to compile zlib support. I think it is by accident available in the original buildroot, but not in mine.
I think it is better to explicitly name it.
During update, RPM cannot simply replace directory by link to direcotry,
therefore create the directory structure and link the files there one by
one (rhbz#1691039).
This avoids issues running `$ bin/rails console --sandbox`, which
otherwise breaks with error such as:
