freebsd32: generate from sys/kern/syscalls.master
This avoids the need to keep a freebsd32-specific syscalls.master in sync with the default ABI. As evidenced by the number of commits required to sync the two, it is extremely easy for them to get out of sync due to misunderstandings and user errors. Reviewed by: kevans, kib
