Create a cpu_loop-common.h for future use by
these new files and use it in the existing
main.c
Introduce target_cpu_copy_regs():
declare the function in cpu_loop-common.h
and an empty function for each target,
to move all the cpu_loop prologues to this function.

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

No code change, only move code from signal.c to
riscv/signal.c, except adding includes and
exporting setup_rt_frame().

As support for RISC-V was only merged into the mainline kernel at 4.15
it is unlikely that glibc will be happy with a reported kernel version
of 3.8.0. Indeed when I testing binaries created by the current Debian
Sid compiler the tests failed with:
FATAL: kernel too old
Bump the version to the minimum a RISC-V glibc would expect:
