Title: php53, php54: fix ambiguous zlib dep

php53 and php54 both have a dependency on "zlib", but because neither josegonzalez/php nor mxcl/homebrew provide a zlib formula this will error out for users who don't have a zlib available from somewhere. It would be better to `depend_on "homebrew/dupes/zlib"`, so the source of the dependency can be tracked for users who don't already have it tapped.

Since the zlib dependency was added to fix bugs in 10.8, this also makes the dependency conditional rather than absolute.
