Adding new exp file for tc18_semabuse in helgrind.
The existing tc18_semabuse.stderr.exp expects that sem_post on a bogus semaphore
will fail, yet it does not on platforms such as MIPS or ARM. This is specific to
implementation of sem_post for i386/x86_64 that has some assumptions such as that
'private' field is not clobbered. This will eventually result in different
parameter passed to syscall and thus different output is encountered.
This change fixes helgrind/tests/tc18_semabuse for MIPS.
