t/solver_git: fix test to work with git <2.29

'git diff --abbrev=40' did not abbreviate /^index / lines of
diff output with git <2.29, and 40 will be insufficient for
SHA-256.  --full-index has been around since 2005, so it's safe
to rely on.

Tested git version 2.20.0 (Debian buster).

Fixes: 751df49e7db8ba77 ("lei rediff: add --drq and --dequote-only")
