Constrain mkdir calls to avoid extra mkdirs

This updates the calls that make the subdirectories for objects
to use a base directory above which git_futils_mkdir won't walk
any higher.  This prevents attempts to mkdir all the way up to
the root of the filesystem.

Also, this moves the objects_dir into the loose backend structure
and removes the separate allocation, plus does some preformatting
of the objects_dir value to guarantee a trailing slash, etc.
