[LTP] [PATCH 1/2] tst_security.sh: Fix SELinux detection

[Petr Vorel]

Some SLES15 versions create /selinux directory which fails the detection
if SELinux is actually not enabled. Therefore detect if directory
actually contains the 'enforce' file.

Also drop /selinux directory detection and detect only /sys/fs/selinux,
/sys/fs/selinux mount point was added in kernel 3.0 in commit
7a627e3b9a2b ("SELINUX: add /sys/fs/selinux mount point to put selinuxfs")
14 years is enough, kernel 3.0 is not even supported in current LTP and
we don't even support /selinux in C API (tst_security.c).

Fixes: e7b804df65 ("shell: Add tst_security.sh helper")
