builtin/repack.c: pass "cruft_expiration" to `write_cruft_pack` 

`builtin/repack.c`'s `write_cruft_pack()` is used to generate the cruft
pack when `--cruft` is supplied. It uses a static variable
"cruft_expiration" which is filled in by option parsing.

A future patch will add an `--expire-to` option which allows `git
repack` to write a cruft pack containing the pruned objects out to a
separate repository. In order to implement this functionality, some
callers will have to pass a value for `cruft_expiration` different than
the one filled out by option parsing.

Prepare for this by teaching `write_cruft_pack` to take a
"cruft_expiration" parameter, instead of reading a single static
variable.

The (sole) existing caller of `write_cruft_pack()` will pass the value
for "cruft_expiration" filled in by option parsing, retaining existing
behavior. This means that we can make the variable local to
`cmd_repack()`, and eliminate the static declaration.
