util/ifittool: Add an option to set the FIT pointer a CBFS file

Browse Source 
The purpose of this is to eventually move the FIT table out of the
bootblock, generate it separately as a cbfs file and then have the FIT
pointer point to that cbfs file.

TESTED: extracted a FIT table using dd, added it as a cbfs file and see
that the FIT pointer correctly points to it. Also test that trying to
add a non valid FIT cbfs file results in an error.
