[PATCH 43/49] repack: extract `write_pack_opts_is_local()`

Similar to the previous commit, the functions `write_cruft_pack()` and
`write_filtered_pack()` both compute a "local" variable via the exact
same mechanism:
const char *scratch;
int local = skip_prefix(opts->destination, opts->packdir, &scratch);
Not only does this cause us to repeat the same pair of lines, it also
introduces an unnecessary "scratch" variable that is common between both
functions.
Instead of repeating ourselves, let's extract that functionality into a
new function in the repack.h API called "write_pack_opts_is_local()".
That function takes a pointer to a "struct write_pack_opts" (which has
as fields both "destination" and "packdir"), and can encapsulate the
dangling "scratch" field.
Extract that function and make it visible within the repack.h API, and
use it within both `write_cruft_pack()` and `write_filtered_pack()`.
The remaining duplication (that is, that both `write_cruft_pack()` and
`write_filtered_pack()` still both call `write_pack_opts_is_local()`)
will be addressed in the following commit.
