userspace: move KOBJECT/PRIVILEGED_STACK_TEXT_AREA to Kconfig

Browse source 
Instead of hardcoding in linker script, use a Kconfig and deal with
dependencies in Kconfig instead of directly in the linker file.

This patch moves both:
PRIVILEGED_STACK_TEXT_AREA
and
KOBJECT_TEXT_AREA

to arch/Kconfig.
