[PATCH v2 29/39] http-fetch: set up git directory before parsing pack hashes

In dd4b732df7 ("upload-pack: send part of packfile response as uri", 2020-06-10), the git http-fetch code learned how to take ac --packfile option. This option takes an argument, which is the name of a packfile hash, and parses it using parse_oid_hex. It does so before calling setup_git_directory.

However, in a SHA-256 repository this fails to work, since we have not
set the hash algorithm in use and parse_oid_hex fails as a consequence.
To ensure that we can parse packfile hashes of the right length, let's
set up the git directory before we start parsing arguments.
