    Merge pull request #2808 from rear/jsmeix-exclude-watchdog
    
    Exclude dev/watchdog* from the ReaR recovery system:
    In default.conf add dev/watchdog* to COPY_AS_IS_EXCLUDE
    because watchdog functionality is not wanted in the recovery system
    because we do not want any automated reboot functionality
    while disaster recovery happens via "rear recover",
    see https://github.com/rear/rear/pull/2808
    Furthermore having a copy of dev/watchdog*
    during "rear mkrescue" in ReaR's build area
    may even trigger a system crash that is caused by a
    buggy TrendMicro ds_am module touching dev/watchdog
    in ReaR's build area (/var/tmp/rear.XXX/rootfs),
    see https://github.com/rear/rear/issues/2798
