osbuild.spec: don't mangle shebangs

Browse source 
Stop the rpm post install script from mangling shebangs for runners,
stages, and assemblers on RHEL. This breaks running them in osbuild
build roots, which might contain a different operating system than the
host, and thus not have platform-python.

This was always the intended behavior, and cb265e8b5 was a step in that
direction.

In effect, this changes a requirement on build roots, because when
building RHEL on RHEL, all current stages and assemblers now have a
python3 shebang. Thus, this means all build roots must have python3
explicitly installed.

Fixes #354
