libredirect: Add support for Darwin

Browse Source 
The library can be used also on Darwin using it like this:

  NIX_REDIRECTS='foo=bar' \
  DYLD_INSERT_LIBRARIES=${libredirect}/lib/libredirect.so \
  DYLD_FORCE_FLAT_NAMESPACE=1 \
  some_program

So let's actually not hardcade gcc and add Darwin to meta.platforms.

No other changes seem to be required.
