gdi32: Use the maximum number of colours when biClrUsed is zero.

Fix a regression from 225004e1. According to MSDN, if the biClrUsed field is zero, the bitmap should
use the maximum number of colours corresponding to the value of the biBitCount member for the
compression mode specified by biCompression.

Revert "wineps: Use the correct colours when a monochrome bitmap without a colour table is the source.".

This reverts commit ad7e889c1d58aec091e72f08db86346c74070128.

Manual tests show that the color table is always used.
