Fix sem_getvalue

[Paul Kunysch <paul dot kunysch at emsys dot de>]

Hello

In 1.7.24 and 1.7.25 sem_getvalue() returns the current value instead of 
setting the out-parameter and returning 0/-1 for success/error.

I attached a simple fix.

I don't know if this should be further improved by setting errno to 
EINVAL if STATUS_INVALID_HANDLE == status.

Unfortunately I wasn't able to run and extend the unit tests.  Running 
"make check" fails with "No rule to make target `dataascii.o', needed by 
`libltp.a'".  The VPATH seems to be extended correctly.

Kind regards,
Paul
