[PATCH] uvcvideo: add another YUYV format GUID

[Daniel Ritz <daniel.ritz@gmx.ch>]

For some unknown reason, on a MacBookPro5,3 the iSight _sometimes_ report
a different video format GUID. This patch add the other (wrong) GUID to
the format table, making the iSight work always w/o other problems.

What it should report: 32595559-0000-0010-8000-00aa00389b71
What it often reports: 32595559-0000-0010-8000-000000389b71
