[arch-projects] [devtools] [PATCH] archrelease: Fix SVN error when repository is empty

[Lukas Fleischer]

If trash is empty, `svn rm -q "${trash[@]}"` fails with:

    svn: Try 'svn help' for more info and then
    svn: Not enough arguments provided

This doesn't result in any further malfunction but is kind of confusing
and unexpected. Skipping `svn rm` on an empty trash fixes this.

Pierre: I also pushed a version that is based on the other pending
patches to my "for-pierre" branch.
