Get rid of released Debian packages when installing trunk release

Inside the pool there might be versions which have been released inside a
maintenance branch but which don't cover recent changes in trunk.

This caused current trunk installations to fail with:

| mv: cannot stat `/etc/ngcp-config/config.yml': No such file or directory

So get rid of every file without "svn" in the filename, so e.g.:

  ngcp-installer-ce_0.7.2+0~1339173026.svn9034.165_all.deb (trunk version)

is preferred over:

  ngcp-installer-ce_0.7.3_all.deb (release into 2.5 repository)

When we're installing trunk we don't care about released versions,
so get rid of them.

Tricky.
