Bug 13871

Additional task from original Bug #13681.

The testimage.bbclass assumes multiple tools will be installed on target for the testimage_dump_target() function [1]. These are NOT common tools for targets.

testimage_dump_target () {
    top -bn1
    ps
    free
    df
    # The next command will export the default gateway IP
    export DEFAULT_GATEWAY=$(ip route | awk '/default/ { print $3}')
    ping -c3 $DEFAULT_GATEWAY
    dmesg
    netstat -an
    ip address
    # Next command will dump logs from /var/log/
    find /var/log/ -type f 2>/dev/null -exec echo "====================" \; -exec echo {} \; -exec echo "====================" \; -exec cat {} \; -exec echo "" \;
}

First of all, these should be in a packagegroup for easy inclusion. Said packagegroup should be mentioned in a comment in the class. The class should check for whether those tools are installed and report a useful error to the user, rather than just a slew of file or path not found type errors.
