linux-user: define TARGET_ARCH_HAS_SETUP_FRAME
Instead of calling setup_frame() conditionally to a list of known targets,
define TARGET_ARCH_HAS_SETUP_FRAME if the target provides the function
and call it only if the macro is defined.
Move declarations of setup_frame() and setup_rt_frame() to
linux-user/signal-common.h
