[SRU F/G/U 2/3] UBUNTU: [Config]: prepare to enforce all

[Thadeu Lima de Souza Cascardo]

BugLink: https://bugs.launchpad.net/bugs/1879327

Add an extra option to config-check script, which means to enforce all
options.  In case it's false, it behaves like before. In case it's true, it
treats all options as enforced.

By default, we call it with a false value, allowing that to be changed in
$(DEBIAN)/rules.d/hooks.mk, for example.
