Title: fixed: build with libshairport without ao_set_metadata

Fix build with libshairport without the
AudioOutput.ao_set_metadata and AudioOutput.ao_set_metadata_coverart
members (which were added to libshairport git two months ago).

A previous commit 537bec4 had already tried to do this, but it did not
work properly and was therefore reverted in f58b70a.
