support/download: cleanup svn backend

Commit 89f5e9893 (support/download/svn: generate reproducible svn
archives) did what it said, but can be siplified a bit.

Indeed, we are doing an svn export, so we won't have any of the .svn
directories, neither at the root of the extract, nor in any of the
sub-directories.

As such, we do not need to filter them out  when we generate the list
of files to include in the archive.
