Found and fixed more missing property interface forwarders.

Probably due to a copy-and-paste error the implementation of
File::removeUnsupportedProperties() contained cases for several type
which do not reimplement this method; for others the implementation was
missing and is now included.

In addition, the formats Speex and Opus suffered from the same bug as
OggFLAC in the commit before, which is now fixed.
