[Buildroot] [PATCHv2 12/12] gitlab-ci: check all defconfigs on every push

[Romain Naour <romain.naour@gmail.com>]

A defconfig check has been introduced by a previous
patch to test each defconfig before the building them.
But those builds are done every week or more.

Checking a defconfig can be done on every push to the
repository since it take few seconds for each.

This would allow to detect as soon as possible a problem
in a defconfig and in particular Kconfig symbols that
disapear from the generated .config file.

Although we could have used one job for each defconfig
check, we need to limit the number of jobs since gitlab
can limit the number of jobs in active pipelines.
(500 by default [1]).

So, add a new job called defconfig_check that test all
defconfig in one go.

The test curently take 3 minutes 31 seconds to run in
a gitlab runner.
