support/scripts/generate-gitlab-ci-yml: make it possible to test multiple defconfigs

Already supported:

 - Pushing a branch called "<foo>-defconfigs" tests all defconfigs.

 - Pushing a branch called "<foo>-defconfig-<defconfig-name>" will
   test one particular defconfig

This commit adds support for:

 - Pushing a branch called "<foo>-defconfigs-<pattern>" which will
   test all defconfigs whose name start with the pattern. For example
   "<foo>-defconfigs-qemu_" will test all Qemu defconfigs
