In current form SHM buffers pixel format can only be printed as 0 and 1.
With the help of this helper we align with DRM_FORMAT_ pixel format.

Add a function to find a format description by the DRM format name. This
will be useful when parsing configuration strings.
While at it, fix the two function formattings in pixel-formats.h to
match everything else in the file.

There is often a need to print the name of a pixel format. Printing the
raw numeric value is hard to decipher, printing the four ASCII
characters is slightly more human-friendly but still needs a decoder
table. Add a name that can be printed easily.
The bulk of this patch was done with:
sed -i -e 's/\.format = DRM_FORMAT_\(.\+\),/DRM_FORMAT(\1),/' libweston/pixel-formats.c

Rather than duplicating knowledge of pixel formats across several
components, create a custom central repository.
