[PATCH 0/2] Support compiling out the prctl syscall

Some embedded systems can do without the prctl syscall, saving some space.

This also avoids regular increases in tinyconfig size as people add more
non-optional functionality to prctl (observed via the 0-day kernel
infrastructure).

The first patch moves prctl and all its helpers into a separate source file,
kernel/prctl.c, to allow making it optional via the Makefile without any
ifdefs. The second patch adds the Kconfig option to make prctl optional.

kernel: Move prctl and helpers from kernel/sys.c to new kernel/prctl.c
kernel: Support compiling out the prctl syscall
