binman: Allow faked blobs in blob-ext-list

Since this is a list of blobs, each blob should have the ability to be
faked, as with blob-ext. Update the Entry base class to set allow_fake
and use the base class in the section code also, so that this propagagtes
to blob-ext-list, which is not a section.
