Relabel filesystem if SELinux is available

Browse Source 
Relabel the filesystem during image builds if SELinux is supported
in the kernel of the build machine and userspace tools are available.

Otherwise touch /.autorelabel to schedule a relabel the first time
the image boots. We relabel when possible because it decreases first
boot time.
