[PATCH 4/9] fetch2/git: keep the gitpkgv commit count numeric

[Anders Heimer <anders.heimer@est.tech>]

The cold-cache path used to keep the raw splitlines() list in
commits while only using len(commits) when writing the cache file.

That same commits value is formatted into the returned version string
below, so cold cache could return a Python list representation while
warm cache returned the numeric count. Store the numeric count in
commits before both writing the cache and building the return value.
