Reorder modutils config options & fix yet more dependency

- modprobe can indirectly benefit from FEATURE_2_4_MODULES and
  FEATURE_INSMOD_TRY_MAP options.
- The position of config FEATURE_INSMOD_TRY_MMAP prevented some other
  config options from indenting under FEATURE_2_4_MODULES. Reorder to
  fix this.
- FEATURE_MODPROBE_SMALL_CHECK_ALREADY_LOADED is now moved to
  Config.src under "Common options" section. (I wished to edit this
  config so that it also work with "big" modutils, but it's not done at
  the moment. Sorry.)
