x86: merge sys_rt_sigreturn between 32 and 64 bits
Impact: cleanup
With the recent changes in the 32-bit code to make system calls which
use struct pt_regs take a pointer, sys_rt_sigreturn() have become
identical between 32 and 64 bits, and both are empty wrappers around
do_rt_sigreturn(). Remove both wrappers and rename both to
sys_rt_sigreturn().
