explicitly splits the packages for kexec and kdump. Thus, rather
than generically install kexec-tools. State explicitly which
tools need to be installed.

kexec is needed to reboot a Linux kernel from Linux. vmcore-dmesg
is needed to extract the dmesg buffer from the /proc/vmcore dump
file.

luv-test-manager: Remove waiting time for removable media

The waiting is done already by the luv-crash-handler. Thus, there
is not need to repeat the waiting here.

luv-crash-handler: Save dmesg buffer to non-volatile media

The dmesg buffer can provide valuable information to determine
the causes of a kernel crash. When the systems boots to
runlevel 3, the luv-crash-handler uses vmcore-dmesg to recover
the dmesg buffer from the vmcore dump and saves it to the LuvOS
test results partition.

This information can then be sent to the developers to investigate
further on the causes of the crash.
