selftests, sched/membarrier: Add multi-threaded test membarrier commands cover very different code paths if they are in a single-threaded vs multi-threaded process. Therefore, exercise both scenarios in the kernel selftests to increase coverage of this selftest.

membarrier: clean up selftest We don't need to specify an explicit rule in the Makefile, the implicit one will do the same. The "__EXPORTED_HEADERS__" define is not needed, because we build the test against the installed kernel headers, not the in-tree kernel headers. Re-use "$(TEST_PROGS)" in the clean target rather than spelling the executable name twice. Include <unistd.h> rather than the rather specific <asm-generic/unistd.h>. Include <syscall.h> rather than <sys/syscall.h>. In both cases, the former header is located in a standard location and includes the latter.
