lib: Fix SSM PUP creation on OS Xbe

OS X doesn't support chmod on shm files after creation. Since we
already set the mode at creation, that call was redundant. Fixed the
getpeereid() function was not accessible because of the guards. Fixed
some differences between macOS and Linux with gid_t vs int usage.
