[Buildroot] [v2, 1/1] systemd: enable selinux if libselinux is selected.

[Adam Duskett]

systemd currently has selinux disabled statically.  This prevents
/sys/fs/selinux from being mounted automatically at boot which
causes audit to no longer function.  This patch fixes the problem
by checking to see if libselinux is selected and enabling support for
selinux if so.

Changes v1 - v2:
 - Added SYSTEMD_DEPENDENCIES += libselinux in the case that
   libselinux was selected.
