BUG: disable 2gb file size check in getid3, which causes problems

The extra check is run only on 32-bit platforms. getid3 ends up calling `ls` via shell, which does not play together with oc:// streamed files opened with fopen.

Only after this change, music files appear in the media player on my server machine. (I.e. the media player is unusable without it.)

Didn't check what happens with > 2GB files with this change. However, that big music files are rather uncommon, and I'd guess getid3 will simply fail to read the tag.
