sha1_name.c: allow get_short_sha1() to take other flags
Instead of a separate "int quietly" argument, make it take "unsigned
flags" so that we can pass other options to it.
The bit assignment of this flag word is exposed in cache.h because
the mechanism will be exposed to callers of the higher layer in
later commits in this series.
