Make configure check for IPC::Run when --enable-tap-tests is specified.

Browse Source 
The TAP tests mostly don't work without IPC::Run, and the reason for
the failure is not immediately obvious from the error messages you get.
So teach configure to reject --enable-tap-tests unless IPC::Run exists.
Mostly this just involves adding ax_prog_perl_modules.m4 from the GNU
autoconf archives.

This was discussed last year, but we held off on the theory that we might
be switching to CMake soon.  That's evidently not happening for v10,
so let's absorb this now.
