Port better to non-GCC compilers

Gnulib now defines _Noreturn for us on pre-C11 compilers,
so use that instead of the less-portable __attribute__ ((noreturn)).
* lib/system.h (__attribute__): Remove; no longer used.
* paxlib/paxlib.h: Use _Noreturn instead of __attribute__ ((noreturn)).
* paxtest/paxtest.c (dump): First arg is char *,
not unsigned char *, to avoid type mismatch.
