allow to start other emulations (eg native code) 

from here: set p_execsw to the new thing, and call
the new emulation's syscall_intern()

XXX there are more differences to kern_exec.c, sa/ras
related afaics, this is harmliss for now since
netbsd32 doesn't support multithreaded programs yet --
one day one execve() implementation should be shared
by native and netbsd32 code.
