Improve ignore handling in git_status_file

The git_status_file API was doing a hack to deal with files that
are inside ignored directories.  The status scan was not reporting
any file in this case, so git_status_file would attempt a final
"stat()" call, and return IGNORED if the file actually existed.

On case-insensitive filesystems where core.ignorecase is set
incorrectly, this magic check can "succeed" and report a file
as ignored when it should actually return ENOTFOUND.

Now that we have the GIT_STATUS_OPT_RECURSE_IGNORED_DIRS, we can
use that flag to make sure that git_status_file() will look into
ignored directories and eliminate the hack completely, so we give
the correct error.
