gst-env.py: Output DYLD_LIBRARY_PATH with --only-environment on macOS

Browse source 
DYLD_LIBRARY_PATH is considered a security risk by Apple, so shells
filter it out, but we can set it when using --only-environment so
people can use it like so:

  eval $(./gst-env.py --only-environment)

This is currently the only way to build an app that links to gstreamer
inside the devenv on macOS and have it run properly.
