php: rework selection of interfaces

Following suggestion of Yann Morin, rework selection of php
interfaces: use booleans instead of choice to be able to select
multiple interfaces as they are not exclusive. We make sure at least
one of the options is selected.

It should be noted that previously CGI and FPM could not be selected
at the same time. This is now possible. Bug that prevented compilation
of CGI and FPM binaries at the same time has been fixed since PHP 5.4
(https://github.com/php-build/php-build/issues/101).

Legacy handling is added for the two options that are removed, and the
appropriate new options are selected.
