Subject: [PATCH] 10_linux.in: Also use GRUB_CMDLINE_LINUX_DEFAULT to set
 kernelopts

The GRUB documentation mentions that there are two variables to set the
linux kernel cmdline: GRUB_CMDLINE_LINUX and GRUB_CMDLINE_LINUX_DEFAULT.

The former is added to all the menuentry commands and the latter is not
added to the recovery mode menu entries. But the blscfg module doesn't
populate recovery entries from the BLS snippets, so the values set in the
GRUB_CMDLINE_LINUX_DEFAULT variable should also be included in kernelopts.

This is needed because the GRUB_CMDLINE_LINUX_DEFAULT option is mentioned
in the GRUB documentation so users assume that the kernel cmdline options
can be changed by setting this option and running the grub2-mkconfig tool.
