Fix conflicts entries based on a script that searches for duplicate
files installed by several ports.
Some patters seem to make ports conflict with themselves, but this is
actually not the case due to the check-*-conflicts logic implemented
in bsd.port.mk, which excludes self-conflicts.
PHP based ports have been ignored in this commit as requested by the
committers currently working on the php-8.1 import.
