Add ConfigConstants.CONFIG_SECTION_LFS

DirCacheCheckout has a warning about non-localised string "lfs". Other
classes use org.eclipse.jgit.lfs.lib.Constants but that is not visible
to DirCacheCheckout.

Add a new constant in ConfigConstants and use that in DirCacheCheckout.

Replace existing uses of org.eclipse.jgit.lfs.lib.Constants.LFS with
the new constant, except where it is referring to the folder name.
