Subject: CI: build: add checks to test if toolchain container can be used

Add checks to test if toolchain container can be used.
This is to handle case of new target or migration of any sort.

If the toolchain container can't be found, the tools container is used
instead.

(cherry picked from commit 23a5c715a9296e828be5c32eadf68eacdb326a0a)
