[Fedora-packaging] Packaging/PHP : add channels packaging proposal.

Here is another update proposal for the PHP Guidelines.

Context : some packages are provided on other channels than the default
one (pear.php.net)

The channel definition must be installed (in the pear registry) to allow
the build, so this require an RPM of channel definition available in the
repository :
- - to build the package in mock.
- - to install the package

Note : i don't keep Requires php, as php-pear already require php and
php-cli.

Regards.
