linux-user/arm: Implement setup_sigtramp
Mirror what the kernel does in arch/arm/kernel/signal.h,
using the old sigframe struct in the rt sigframe struct.
Update the trampoline code to match the kernel: this uses
sp-relative accesses rather than pc-relative.
Copy the code into frame->retcode from the trampoline page.
This minimises the different cases wrt arm vs thumb vs fdpic.
