commands.rb: Ignore .git directories instead of .svn when uploading update

When doing the migration to git, we neglected to modify the exclude
list for the updater upload from .svn to .git.  This means that we're
copying all of the history up as well, which substantially slows the
build process.  This patch changes the exclude from .git to .svn.
