profiles: add "php7-0" to PHP_TARGETS in base/make.defaults.

The old value of the PHP_TARGETS variable was "php5-6", but these days
PHP_TARGETS="php5-6 php7-0" is more appropriate. The rationale for
this change is now included as a comment above the variable.

Closes: https://bugs.gentoo.org/636692
