init/Kconfig: update KALLSYMS_ALL help text 



CONFIG_KALLSYMS_ALL is required for kernel live patching which is a
common use case that is enabled in some major distros. Update the
Kconfig help text to reflect that.

While at it, s/e.g./i.e./ to match the text intention.

	  size (depending on the kernel configuration, it may be 300KiB or
