[LTP] [PATCH] tst_security.sh: quote variables in selinux helper functions

[Avinesh Kumar]

From: Avinesh Kumar <avinesh.kumar@suse.com>

Quote variables in tst_disable_selinux() and tst_update_selinux_state()
to follow shell quoting best practices.

Fixes: cc9206e612b2 ("tst_security.sh: Use enforce toggle to trigger SELinux measurement")
