tests/ipc_sem: detect broken kernels

Browse Source 
When running 32bit ipc tests on ppc/sparc with a 64bit kernel, the ipc
logic wrongly returns errors.  Detect that and throw an error.

* tests/ipc_sem.c: Return 99 when errno is EFAULT.
* tests/ipc_sem.test: Save output to $OUT and show it when failing.
Handle exit status 99 to throw an ERROR.
