gitlab-ci: convert only/except to rules

only/except keywords will be deprecated by upcoming gitlab release,
upstream recommend to use rules keyword instead [1][2][3][4][5].

This patch convert .gitlab-ci.yml to use rules, no functional
changes intended.

After this patch, we should still have the following behaviour
while pushing commit, tag, branches:

     - to trigger only the check-* jobs:
       $ git push gitlab HEAD:<name>

     - to trigger all defconfigs and all check-* jobs:
       $ git push gitlab HEAD:<name>-defconfigs

     - to trigger all runtime tests and all check-* jobs:
       $ git push gitlab HEAD:<name>-runtime-tests

     - to trigger one defconfig job:
       $ git push gitlab HEAD:<name>-<defconfig name>

     - to trigger one runtime job:
       $ git push gitlab HEAD:<name>-<test case name>
