pore doesn't work with safe.bareRepository=explicit

[rprichard]

Git recently added a new security feature (safe.bareRepository=explicit) that disables git's automatic detection of bare repositories. It breaks pore:

rprichard@rprichard:/x/aosp$ pore sync
[00:00:00] fetching       1/1 ########################################: 
platform/manifest: failed to fetch for project platform/manifest

Caused by:
    git fetch failed: fatal: cannot use bare repository '/home/rprichard/pore-data/android/objects/platform/manifest.git' (safe.bareRepository is 'explicit')
    
fatal: failed to sync

AFAIK the git project's default is still safe.bareRepository=all, but my computer has it set to explicit.

I think passing any of GIT_DIR, --git-dir, or --bare to git would fix this issue.
