[LTP] [PATCH] locking/lock_torture: accept optional "[debug]" in result string

[Vincent Chen]

lock_torture.sh parses the lock_torture result from dmesg by
matching the "End of test: <RESULT>:" line.

When the kernel is built with lock debugging enabled (e.g.
CONFIG_DEBUG_MUTEXES, CONFIG_DEBUG_RT_MUTEXES, CONFIG_DEBUG_SPINLOCK),
lock_torture may print "End of test: SUCCESS [debug]: ...".
The current regexp expects "SUCCESS:" and fails to match, causing the
test to be reported as failure.

Allow an optional " [debug]" token between the result string and the
colon so the test can correctly detect SUCCESS on debug kernels.
