bitbake: bitbake-diffsigs: add an option to find and compare specific signatures 

With the -t option which recurses to find the ultimate cause of a
signature change, it was hardcoded to take the last two executions of
the specified task. On the other hand, if you have two specific task
hashes (say from bitbake output, or some other tool) then you'll want to
pick those, so provide an option to specify those as well. (Note, the
new -s option needs to be specified alongside -t rather than instead of
it.)

(Bitbake rev: d9813b1a4223cf8dc80cab90e467ddf4bf8d1078)
