install-deps.sh: install python3-devel for python related rpm macros

python3-devel depends on python-rpm-macros, which in turn depends on
python-srpm-macros. the latter offers `python3_pkgversion` macro, which
is necessary for prepare the build dependencies of rpm packages.

this change avoids the unnecessary `$yumdnf` calls, and to simplify the
code.
