The generated asm/unistd_compat_32.h header file now contains
macros that can be used directly in the vdso and the signal
trampolines, so remove the duplicate definitions.

Kuser code should be inside .rodata. sigreturn32.S is splited
from kuser32.S, the code in .text section is never executed.
Move it to .rodata.

To make it possible to disable kuser helpers in aarch32 we need to
divide the kuser and the sigreturn functionalities.
Split the current version of kuser32 in kuser32 (for kuser helpers)
and sigreturn32 (for sigreturn helpers).
