www/glpi: Update version 0.90.3 => 0.90.5 and change option defaults

Per request [1], the IMAP and LDAP options have been set to ON by default.
The maintainer took the opportunity to upgrade the version [2].
I converted the options to their modern equivalents and made the
MASTER_SITES definition more generic to help future upgrades.
