    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")
    Signed-off-by: Christian Marangi <ansuelsmth at gmail.com>
    (cherry picked from commit 65c3d19c4b28ccac0d08d916de0ffa4c0e7b3dc2)
