gitfs: Include file mode in find_file results
gitfs: Include file mode in find_file results

Since we're only going to be using the stat information for mode
manipulation, there is no need to waste CPU resources by stat'ing the
file. Besides, only the mode information is stored in the git metadata,
so the remaining params from a posix.stat_result would be inaccurate and
all but useless to us.
