object-file: mark unused parameters in hash_unknown functions 

The 0'th entry of our hash_algos array fills out the virtual methods
with a series of functions which simply BUG(). This is the right thing
to do, since the point is to catch use of an invalid algo parameter, but
we need to annotate them to appease -Wunused-parameters.
