David 4f1ae1cc3a feat(libkernel): implement execv and execve as throwing exports
XPSemu PPSA97358 imports both from libkernel.prx; with the imports ahead
of them covered, its predicted next stops (relink registry order, not an
observed run) are:

  FAIL: unresolved ELF import KaK52lYTBIs from libkernel.prx  (execv, 7 call sites)
  FAIL: unresolved ELF import kdguLiAheLI from libkernel.prx  (execve, 4 call sites)

Today the title stops earlier at the observed
  FAIL: unresolved ELF import aRo9AhFUXcM from libkernel.prx  (sigsetjmp, merged in #3486)

As for execvp (#2827), the process image cannot be replaced here, so both
throw with the execvp message pattern once FreeBSD 11's execve would start
loading the image (freebsd-src 8c639945, sys/kern/kern_exec.c
exec_copyin_args, do_execve, exec_check_permissions; lib/libc/gen/exec.c
execv passes environ). Before that they fail as FreeBSD does: EFAULT for a
null argument vector or path, ENOENT and ENOTDIR from the lookup as stat
reports it, EACCES for a path that is not a regular file. Paths of
PATH_MAX bytes or more and strings over ARG_MAX throw instead of guessing
the console's limits. The execv calls in XPSemu's sources run in a fork
child (net/tap.c), and its fork fails with ENOSYS (ZiZc3/XPSemu 8eec07b4,
ps5/compat/libc_missing.c, ps5/build-title.sh --defsym).

NIDs computed with tools/nid_names.py and confirmed in aerolib.
