Allow to compile out serprog completely

If CONFIG_SERPROG is not set, no stubs and no data of serprog will
remain.

Side benefit: This kills a few dozen lines of code.

r678, r679 and r680 made this possible. Once "Only list available
programers in usage()" is committed, even the usage message will be
adjusted automatically.

Corresponding to flashrom svn r681.
