php80 package: PHP 8.0.3 was added to pkgsrc

[Takahiro Kambe <taca%NetBSD.org@localhost>]

Hi,

I've added lang/php80 (PHP 8.0.3 now) to pkgsrc.

* textproc/php-json is included in lang/php80 since PHP 8 dose support
  disable or build separately json extension any more.

* net/php-xmlrpc is dropped from PHP 8.  php-xmlrpc use xmlrpc-epi
  (<https://sourceforge.net/projects/xmlrpc-epi/>) internally but
  it was abandoned.  So, these PHP packages should be stop depending
  php-xmlrpc in future.

	www/php-glpi
	www/php-tiki6

Best regards.
