Add 70_mod_php.conf.in to the project source.

We are currently shipping 70_mod_php.conf as part of the Gentoo ebuild
for eselect-php. This introduces a potential disconnect between the
path in php.eselect and the path in 70_mod_php.conf. By adding the
conf file to the project, we are able to ensure that they are both
set to the same value. Moreover, the new autotools directory magic
lets us set them both based on @localstatedir@. So, for example, in
the conf file we have "@localstatedir@/lib/eselect-php/mod_php.conf"
and in php.eselect we have "@localstatedir@/lib/eselect-php".

We have followed the PHP project's lead in assuming that
$localstatedir will be set to (for example) /var and not /var/lib.
See Gentoo bug 572002. For testing, you should now use something like,

  ./configure --bindir=/usr/bin --sysconfdir=/etc --localstatedir=/var

Of course, the ebuild for eselect-php will automatically pass the
correct values to ./configure.
