ui/ncurses: Add preboot check option in the config screen
Petitboot might run some checks to validate the kernel images before
call the kexec load. This patch adds both 'preboot check' option in the
config UI screen and a NVRAM variable 'petitboot,preboot-check' to make
the user choice persistent.
The 'preboot check' is enabled by default. The 'petitboot,preboot-check'
is created on NVRAM only when 'preboot check' is disabled by the user.
NVRAM property changed to preboot-check, small label changes and help
text added by Jeremy Kerr <jk@ozlabs.org>.
