Use defined constants for permission values. Also add fallback definitions for them in system.h, to allow for compatibility with systems that don't provide these macros. Include system.h in all tests/ files that required it. Signed-off-by: Érico Rolim <erico.erc@gmail.com> Signed-off-by: Mark Wielaard <mark@klomp.org>
