    stripper: Handle capabilities
    
    During the build process, we set capabilities to elevate privileges of
    certain progrems (e.g. ping). These have been removed during the build
    process because of strip.
    
    This patch collects any capabilities from all files that are being
    stripped and restores them after calling strip.
    
    Fixes: #12652
