refs: drop "broken" flag from for_each_fullref_in()

No callers pass in anything but "0" here. Likewise to our sibling
functions. Note that some of them ferry along the flag, but none of
their callers pass anything but "0" either.

Nor is anybody likely to change that. Callers which really want to see
all of the raw refs use for_each_rawref(). And anybody interested in
iterating a subset of the refs will likely be happy to use the
now-default behavior of showing broken refs, but omitting dangling
symlinks.

So we can get rid of this whole feature.
