This patch adds the usercrash client in the pipe of core_pattern without affecting default core_pattern program. In acrnprobe_prepare.sh, core_pattern will be set as usercrash-wrapper with all of the arguments, which parses the parameters of the default core_pattern program and the usercrash client, and then invokes them separately.
