php: fix phar build failure for CLI

Disable the phar command-line tool since it requires php to pack itself
up. Fixes build failure for CLI (or CLI+CGI) variants of php.
Hardly useful for embedded scenarios.

+Disable the 'phar' command-line tool build/installation since it requires
+php to run and pack up phar itself in phar format. This would require
+a host-php instance and really probably nobody needs the phar tool
+on the target.
