Cygwin: testsuite: Update mutex tests for changed default mutex type

Default mutex type is PTHREAD_MUTEX_NORMAL.

Attempting to unlock an unowned mutex of that type is specified as
undefined behaviour, not returning EPERM.

mutex7e verfies that attempting to unlock an unowned mutex of type
PTHREAD_MUTEX_ERRORCHECK returns EPERM.
