www/mod_auth_pgsql2 should be disabled for apache24

[Andreas Nilsson]

Hello,

I found out that www/mod_auth_pgsql2 does not play well with apache24:

httpd: Syntax error on line 534 of /usr/local/etc/apache24/httpd.conf:
Syntax error on line 3 of /usr/local/etc/apache24/Includes/my-ssl.conf:
Cannot load libexec/apache24/mod_auth_pgsql.so into server:
/usr/local/libexec/apache24/mod_auth_pgsql.so: Undefined symbol
"ap_requires"

Since ap_requires was removed for ap24 there is no need to build it for
ap24.

Best regards
Andreas
