Fix UnboundLocalError in utils

If the command failed, it would enter the `except` block where we simply
just continue, which would use `output` before it was assigned. This
commit fixes this by defining `output` to empty string.

Make cilium-labels option available globally

It doesn't make sense to restrict this option to sysdump, and having it
restricted to sysdump causes issues like #69. Fix it by making it a
general option in the standard args parser.

Fixes: #69
