fbrnch build should take update options

[Elliott Sales de Andrade]

Since fbrnch build creates an update for non-Rawhide, it should take options for the update, e.g., bugs to reference and update type. (Though I guess for the former I could start putting that in the changelog.)

You are right - currently build reads bugs from the rpm changelog
(I feel it is good practice and helpful to reference bugs there),
but yeah I can add an option for referencing bugs.
There may be cases where one only wants a bug per package say, I think that will be harder to handle without interactive input.
It may well be good to add this to parallel too - maybe when switching it to use sidetags by default.

I haven't tested this end-to-end but believe it should work (Haskell types:-)
