MFC r289441:

Integrate tools/test/posixshm and tools/regression/posixshm into the FreeBSD
test suite as tests/sys/posixshm

Some other highlights:
- Convert the testcases over to ATF
- Don't use hardcoded paths to /tmp (which violate the ATF/kyua samdbox); use
  mkstemp to generate temporary paths for non-SHM_ANON shm objects.
