Currently installing board_inspector deb would overwrite the grub
default kernel CMDLINE GRUB_CMDLINE_LINUX_DEFAULT. This could lose
some useful kernel args configured by user.
This patch is to change the 'overwrite' operation to 'append'.
Simply appending new CMDLINE to GRUB_CMDLINE_LINUX_DEFAULT could
not work. We need to remove duplicated args, and keep the args in
its origin order.

This patch is about the bug that VMs can't idle.
ACRN enables VM's C-state by extracting host's C-state table.
The C-state table has two types of interfaces: system-IO and mwait. VMs
just need one of them. ACRN can support both.
Currently we are telling users to use the system-IO type. That is, by
adding 'nomwait intel_idle.max_cstate=0' to host Linux's CMD line when
using board_inspector. (The reaseon we were using system-IO is that
mwait was buggy on Apollo Lake.)
But recent tests show that system-IO is somehow buggy. Linux c-state
driver(no matter intel_cstate or acpi_cstate) fails to enter idle state
with system-IO. This can always be reproduced on native environments.
MPERF counters show CPU cores are not in real idle state as expected.
To enable C-state in VMs, we have to switch to mwait.
As ACRN has already supported both system-IO and mwait, we don't have
to modify any code. We just need to tell user to use mwait instead of
system-IO.
That is, don't add 'nomwait intel_idle.max_cstate=0' to host Linux's
CMD line when using board_inspector. Just add 'intel_idle.max_cstate=0'
Due to the Apollo Lake's mwait bug, 'nomwait' is still needed for
Apollo Lake as an exception.
