    Fix software deploy precheck failure for patches

    The patch release may not contain deploy-precheck script and will
    cause failure when run 'software deploy precheck <patch release>'.
    This change will skip precheck in case of patches if script is not
    available.

    Test Plan:
    PASS: Upload a patch without 'deploy-precheck' and execute precheck
          (Eg. $ software upload ./inservice-patch-24.03.1.patch
               $ software deploy precheck starlingx-24.03.1)
