libcamera: Fix 90/270 degree transforms

Browse source 
`Transform::Rot90` means the client should rotate 90 deg. clockwise,
which matches `SPA_META_TRANSFORMATION_90`, i.e. the buffer was
rotated 90 deg. anti-clockwise. The flipped cases should be correct
though.

Also add the source value to the debug print for easier future
debugging.
