tests: export GIT_DIR=. after cd into bare repos

Add `GIT_DIR=. && export GIT_DIR &&` after `cd <bare> &&` (105 matches, 45 files).

Mechanical verification (the awk script undoes the
transformation on the new lines; empty output is success):

    git diff HEAD^! | awk '
      /^diff/,/^\+\+\+/ { next }
      /^-/ { old[m++] = substr($0,2) }
      /^\+/ {
        new = substr($0,2)
        # undo: strip GIT_DIR export
        gsub(/ GIT_DIR=[.] && export GIT_DIR &&/, "", new)
        if (old[n++] != new) print old[n-1] " != " new
      }'
