test-read-cache: setup git dir

b1ef400e (setup_git_env: avoid blind fall-back to ".git") made programs
that tried to access a repository without initializing properly die with
a diagnostic message.  One offender is test-read-cache, which is used in
p0002.  Fix it by calling setup_git_directory() before accessing the
index.
