fixup! gvfs-helper: create tool to fetch objects using the GVFS Protocol

This fixup updates b46ad0a (gvfs-helper: create tool to fetch objects
using the GVFS Protocol, 2019-08-13) in reaction to f6f236d
(packfile: refactor `install_packed_git()` to work on packfile store,
2025-09-23) which is included in Git 2.52.0.

The refactored packfile store includes an automatic inclusion of new
packifles into the MRU list. This introduces a bug in microsoft/git's
use of the GVFS protocol in the following scenario in 'git fetch':

 1. If the prefetch downloads at least one prefetch packfile, then it is
    added to the MRU list twice, creating an infinite loop.

 2. If the refs that are updated include commits that are not present in
    the packfile list, then the MRU lookup will iterate through without
    interruption, hitting the infinite loop.

The fix is to modify this patch to no longer include a custom "add to
MRU" method now that the default implementation does this for us.
