Rebuilding RPMs fails due to incorrect buildroot on F41

[antheas]

When rebuilding an rpm from an rpm on F41, it fails with the following:

It appears that in F41 the buildroot define does not work, and rpmbuild tries to use BUILD/pkgname/BUILDROOT and fails since the files are not there.

The following patch fixes it:

sed -i -e 's/args = \["rpmbuild", "-bb"\]/args = \["rpmbuild", "-bb", "--buildroot", "#{build_path}\/BUILD"\]/g' /usr/local/share/gems/gems/fpm-*/lib/fpm/package/rpm.rb

Essentially, adding the arg --buildroot to rpmbuild. That arg says it is deprecated however a quick search online finds no replacement... As to what happened to --define buildroot <root> I do not know.

A reproducer that is runnable via podman (or docker) if this is needed for the maintainers to confirm the problem (and the fix as proposed in #2082):

The same reproducer with FEDORA_VERSION=40 works fine with the current code.
