CI: fix matching for openwrt release branch for container selection

The current match logic doesn't handle test for push events related to
stable release (example openwrt-22.03) but only fork with the related
prefix (example openwrt-22.03-fixup)

Fix wrong matching and while at it also add extra checks to other
matching (check if the branch name actually start with the requested
prefix)

Fixes: abe8a4824210 ("CI: build: add support for per branch tools container")
