disable module support

This substantially improves the granularity of CFI by allowing the
compiler to identify that a massive number of functions called be
indirectly called due to never having their address taken.

The CONFIG_KPROBES option depends on CONFIG_MODULES so it gets disabled
too.

The CONFIG_DIAG_CHAR, CONFIG_HW_RANDOM and CONFIG_BACKLIGHT_CLASS_DEVICE
options use 'default m' and no longer need that overridden since they
get built-in by default now.
