f6a2452d4c Only append DIB_BOOTLOADER_DEFAULT_CMDLINE to default grub entry
The grub.cfg has two variables [1]

 GRUB_CMDLINE_LINUX : used on all boots
 GRUB_CMDLINE_LINUX_DEFAULT : additionally used on all "normal" boots

The problem with I2298675dda1f699c572b3423e7274bc8bd7c1c9d is that it
appened the values in DIB_BOOTLOADER_DEFAULT_CMDLINE to both of these,
resulting in duplicated arguments.  I don't think we considered that
GRUB_CMDLINE_LINUX_DEFAULT actually already appends to the
GRUB_CMDLINE_LINUX values.

Make DIB_BOOTLOADER_DEFAULT_CMDLINE only append itself to
GRUB_CMDLINE_LINUX_DEFAULT.  That seems to line up sensibly with the
name of the variable.

Documentation is enhanced around this, and a releasenote added.
