#43191: openbrowser: remove hardcoded "Perl 5.12" dependency

-------------------------+--------------------------
 When trying to remove Perl 5.12 packages from my system, I found out that
 through a long dependency list openbrowser was installed which requires
 {{{
 depends_run port:p5.12-mac-propertylist
 }}}
 It would be great to change the port in such a way that any perl version
 could satisfy the dependency, in particular now when 5.16 became the
 default version.
