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.

Update the membarrier syscall self-test to match the membarrier
interface. Extend coverage of the interface. Consider ENOSYS as a
"SKIP" test, since it is a valid configuration, but does not allow
testing the system call.
