[PATCH] python/sepolicy: Revert "Only invoke RPM on RPM-enabled Linux distributions"

[Petr Lautrbach <plautrba@redhat.com>]

Commit 8ad76337d09d4b0080275d74392a258ea4ed0273 ("Only invoke RPM on RPM-enabled
Linux distributions") used platform.linux_distribution() function to detect
whether the system is rpm based. This function is deprecated since Python 3.5
and it's removed from Python 3.8 - https://bugs.python.org/issue28167

The original problem is already fixed by another commit
671f83b42ba2 ("policycoreutils/sepolicy: Check get_rpm_nvr_list() return
value"):

    $ sepolicy generate --customize -p mypolicy -n testpolicy -d httpd_sys_script_t -w /home
    Failed to retrieve rpm info for selinux-policy
    Created the following files:
    mypolicy/testpolicy.te # Type Enforcement file
    mypolicy/testpolicy.if # Interface file
    mypolicy/testpolicy.fc # File Contexts file
    mypolicy/testpolicy_selinux.spec # Spec file
    mypolicy/testpolicy.sh # Setup Script

Fixes:
     File "/usr/lib/python3.8/site-packages/sepolicy/generate.py", line 1384, in generate
       if (platform.linux_distribution(full_distribution_name=0)[0] in ("redhat", "centos", "SuSE", "fedora", "mandrake", "mandriva")):
     AttributeError: module 'platform' has no attribute 'linux_distribution'
