[PATCH 08/20] packfile: pass down repository to `unpack_compressed_entry`

[Karthik Nayak <karthik.188@gmail.com>]

The function `unpack_compressed_entry` currently relies on the global
variable `the_repository`. To eliminate global variable usage in
`packfile.c`, we should progressively shift the dependency on
the_repository to higher layers. Let's remove its usage from this
function.
