On systems with merged-sbin, /usr/sbin is a symlink to /usr/bin
(https://fedoraproject.org/wiki/Changes/Unify_bin_and_sbin).
As reported in the Fedora Python channel,
python3 -c 'import sys; print(sys.executable)'
now returns /usr/sbin/python3 rather than /usr/bin/python3.
We don't want the symlinked directories in the $PATH at all.
This implements https://pagure.io/setup/issue/51.
The "upstream" is only used to build the package in our dist-git, so we can reduce the
total amount of work by moving files downstream and maintaining them there.
The package after the rebuild is identical, except for intentional changes
(removal of Group, updating of Url, bumping of the Version):
$ rpmdiff -iT noarch/setup-2.14.5-2.fc41.noarch.rpm noarch/setup-2.15.0-1.fc41.noarch.rpm
