syscall: unify common syscall defines
Unify all the common syscall defines in syscalls-common.h and scrub all the duplicated code from relevant ports. This should also make converting existing ports to INLINE_SYSCALL() much easier as they don't have to get lost in all the unrelated noise, as well as creating new ports.
