[LTP] [PATCH v2 1/2] lib/test.sh: Remove temporary directory only if we know the location

[Petr Vorel]

This is a problem when a test TCONF before calling tst_tmpdir, but has
tst_rmdir in cleanup function (e.g. dhcp_lib.sh when failing on
tst_check_cmds).

Now it has the same behaviour as deleting $TST_TMPDIR in tst_do_exit
in tst_test.sh.
