[PATCH] tests: fix skipping in some tests

[Pádraig Brady]

* tests/cp/cp-a-selinux.sh: Use 'skip_' rather than the probably
undefined 'skip'.
* tests/du/2g.sh: Likewise.
* tests/install/install-Z-selinux.sh: Likewise.
* tests/misc/chcon.sh: Likewise.
* tests/misc/selinux.sh: Likewise.
* tests/mkdir/restorecon.sh: Likewise.
* cfg.mk (sc_prohibit-skip): A new syntax check to catch the issue.
