UBUNTU: [Packaging]: config-check: some enforcement is ignored

Whenever config-check finds an entry like:

CONFIG_VFIO mark<ENFORCED>note<LP#1636733>

it will consider mark<ENFORCED>note as the option name, as the regexp allows
any characters not in the whitespace class (\S). By using a class like [^\s<],
that is, not whitespace and not '<', it will be correctly parsed.

We could fix the entries that have this problem, but fixing the parser is more
robust.

Ignore: yes
