[PATCH] gitlab-ci.yml: Fix the filtering for the git submodules

[Thomas Huth]

Commit 7d7dbf9dc15be6e introduced a new line starting with
"GIT_SUBMODULES_ACTION=" in the config-host.mak file. The grep that
tries to determine the submodules in the gitlab-ci.yml file matches
this new line, too, causing a warning message when updating the modules:

 warn: ignoring non-existent submodule GIT_SUBMODULES_ACTION=update

Fix it by matching the "GIT_SUBMODULES=..." line only.
