libfdk-aacdec: Reduce the default decoder delay by one frame

The default error concealment method if none is set via
aacDecoder_SetParam(AAC_CONCEAL_METHOD) is set in
CConcealment_InitCommonData within the fdk-aac library
and is set to Energy Interpolation. This method requires one frame
delay to the output. To reduce the default decoder output delay and
avoid missing the last frame in file based decoding, use Noise
Substitution as the default concealment method.

Do not detect jp2 images as mov files.
Assume that old bmps do not contain transparency information.

Fixes MK50TEMP.BMP that has its RGB channel bit masks on the actual image.
Use os/2 palette even if it contains less than 256 entries.

Fixes 11Bios13.bmp.
