php5x-zmq: fix extension version that is reported to php

fixes issue #1105
Stop using realpath when requiring files

These days Homebrew follows the symlink before loading the formula file.
This means that __FILE__ will always be the path of the formula file,
and not the symlink in the main Formula directory, so we don't need to
canonicalize it anymore.
