Bug when doing make test using root user

Hi,

I tried to compile git 2.4.3 using root on a server. It failed on test 41 of t0302-credential-store.sh In fact even if we remove read access on a directory, root still can acces this directory. Using a not privilegied user make the test work. Perhaps the test should be adapted to this corner case. Trace below.

Have fun,
