cbfstool: Build vboot library

Currently cbfstool cherry-picks a few files from vboot and hopes these
files will work standalone without any dependencies. This is pretty
brittle (for example, CL:2084062 will break it), and could be improved
by building the whole vboot library and then linking against it.
Therefore, this patch creates a new target $(VBOOT_HOSTLIB) and includes
it as a dependency for cbfstool and ifittool.

To prevent building the vboot lib twice (one for cbfstool and the other
for futility) when building coreboot tools together, add the variable
'VBOOT_BUILD' in Makefile to define a shared build path among different
tools so that vboot files don't need to be recompiled.

Also ignore *.o.d and *.a for vboot library.

     compiled only once
