Turn execvpe() into an internal libc routine.

Adding exevpe() has caused some ports to break. Even though execvpe() is
a useful routine, it does not conform to any standards.

This patch is a little bit different from the patch sent to the mailing
list. I forgot to remove execvpe from the Symbol.map (which does not
seem to miscompile libc, though).
