    Make keepalived configuration future-proof

    As keepalived, from v2.0.0, uses execev() instead
    of system() for running scripts, the haproxy_check
    and the pingable_check will fail when upgrading
    keepalived. Exporting the full command into scripts
    make them compatibale with newer version of keepalived.
