config-tools: board_inspector deb appends kernel CMDLINE

Browse Source 
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.

Tracked-On: #7402
