When calling "sepolgen generate" to automatically generate a SELinux
policy template, the command fails when it cannot invoke RPM related
commands on Linux distributions that do not support RPM by default:
Failed to retrieve rpm info for selinux-policy

TypeError: 'NoneType' object has no attribute '__getitem__'
As the RPM related steps are only needed on RPM-enabled distributions,
we should ignore these steps on other Linux distribution platforms.
In this patch, we use the Python platform module to get the Linux
distribution, and only start the RPM-related activities on Linux
distributions that use RPM as their native package manager.
