um: always include kconfig.h and compiler-version.h

Browse Source 
Since commit a95b37e20d ("kbuild: get <linux/compiler_types.h> out of
<linux/kconfig.h>") we can safely include these files in userspace code.
Doing so simplifies matters as options do not need to be exported via
asm-offsets.h anymore.
