Commit b60daf05

 (Make git-prune-packed a bit more chatty. - 2007-01-12)
changes the meaning of prune_packed_objects()'s argument, from "dry
run or not dry run" to a bitmap.

It however forgot to update prune_packed_objects() caller in
builtin/prune.c to use new DRY_RUN macro. It's fine (for a long time!)
but there is a risk that someday someone may change the value of
DRY_RUN to something else and builtin/prune.c suddenly breaks. Avoid
that possibility.

While at there, change "opts == VERBOSE" to "opts & VERBOSE" as there
is no obvious reason why we only be chatty when DRY_RUN is not set.
