Make internal_fork and internal_exec static

* defs.h: Remove declarations of internal_fork and internal_exec.
* process.c: Remove definitions of internal_fork and internal_exec.
* syscall.c: Move them here.
(internal_syscall): Return void instead of int. We were always
returning zero, and callers weren't checking it anyway.
