kern-tools: make patches with shell-unsafe characters valid

If a patch contains characters like ; or (), it can cause processing
errors in the patch queue.

We had previously fixed this issue by renaming the patches to not
include invalid characters, but with this change to the kern tools
that ensures patch names are wrapped in quotes, we avoid shell
processing and hence they are valid.
