x86, bootup: add built-in kernel command line for x86 (v2)
Allow x86 to support a built-in kernel command line. The built-in
command line can override the one provided by the boot loader, for
those cases where the boot loader is broken or it is difficult
to change the command line in the the boot loader.

OK. This version changes absolutely nothing if CONFIG_CMDLINE_BOOL is not
set (the default). Also, no space is appended even when CONFIG_CMDLINE_BOOL
is set, but the builtin string is empty. This is less sloppy all the way
around, IMHO.
Note that I use the same option names as on other arches for
this feature.
