Fix notmuch_message_maildir_flags_to_tags to iterate over filenames

As documented, this function now iterates over all filenames for the
message, computing a logical OR of the flags set on the filenames,
then uses the final result to set tags on the message.

This change fixes 3 of the 10 maildir-sync tests that have been
failing since being added.
