Fix config order of precedence, putting kernel command line over system.
The correct order of precedence when reading the base config:
builtin config
system config
kernel command line provided config.
This reverts commit 63501f44, which actually broke the behavior it
reported to fix. It also adds some unit tests to ensure this behavior
is not broken again.
LP: #1582323
