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.
