lib{c,sys}: move auxargs more firmly into libsys Continue to filter the public interface (elf_aux_info()), but entierly relocate the private interfaces (_elf_aux_info(), __init_elf_aux_vector(), and __elf_aux_vector) to libsys. This ensures that rtld updates the correct (only) copy of __elf_aux_vector. After 968a18975adc9c2a619bb52aa2f009de99fc9e24 updates were confused and __getosreldate was failing, causing the system to fall back to compat compat12 syscalls in some cases. Return to explicitly linking libc to libsys and link libthr with libc and libsys (in that order).
