manpage: fix places that still treat FourCCs and pixel formats equal 

The video filter chain traditionally used FourCCs for pixel formats.
This was recently changed, but some parts of the manpage were not
updated properly. Now there are two rypes of options: some which take
a FourCC (as used with raw video formats), and some which take a
symbolic format identifier (as used in the video filter chain).

I realize that it's harder to specify FourCC for RGB formats now (TV
stuff may need RGB). They use non-printable characters as part of the
FourCC, and have to be specified as hexadecimal numbers (instead of
a symbolic identifier). Because I can't be bothered to find out what
these numbers are for the respective formats, just remove the old
pseudo-FourCCs from the documentation.
