[Buildroot] [PATCH v7 3/4] support/download: silence svn if it is a silent build

[Fabio Porcedda]

If it is a silent build (make -s -> QUIET=-q) silence the svn download
helper using "svn -q" just like others download helpers, e.g. wget.

Notes:
    v7:
     - use "backend_quiet" instead of "quiet" in the dl-wrapper
    v6:
      - Use QUIET instead of BR_QUIET
    v5:
      - Use getopts
    
    v4:
      - Instead of changing the "SVN" variable pass the "-q" option to the
        download helper (Thomas P.)
    v3:
      - Add this patch
