Subject: [PATCH] syscall: remove mksysnum_darwin.pl script

Direct syscalls using syscall numbers are no longer supported on darwin
since Go 1.12, see https://golang.org/doc/go1.12#darwin. Also,
/usr/include/sys/syscall.h is no longer available on recent macOS
versions, so remove the generating script.
