Disable track metadata export for .ogg files and TagLib 1.11.1

[uklotzde]

Just an ugly workaround for https://bugs.launchpad.net/mixxx/+bug/1833190 and taglib/taglib#864.

Wait, do we know if this only affects OGG/Vorbis or any OGG container file?

[uklotzde]

According to the analysis in taglib/taglib#864 only Ogg files are affected.

I will restrict the workaround to Ogg file access instead of writing VorbisComment tags as now.

[uklotzde]

I've force pushed a different version that restricts the workaround to write access of TagLib::Ogg::Vorbis::File

This compile-time check is still insufficient and the wrong strategy. What we actually need is a runtime check, because on most platforms TagLib is linked dynamically. I'm not aware of any function that accomplishes that.

I'm really concerned about the way such a critical bug in one of our basic dependencies is handled. Unfortunately there is currently no alternative for TagLib.

What is the scenario, such a check is required? On Linux we can rely on the package manager.
On the other systems we install the right version ourselves. If one messes around with the libraries, it is his own responds to set up a working version or not.

@Pegasus-RPG merge?
And release 2.2.2 short after?

[uklotzde]

Let's just rely on the static build time check. It should be sufficient for most use cases.

Anything else to do? We should release this asap to prevent further damage.

[daschuer]

OK

I'll resolve the conflicts with master, caused by reformatting.
