linux-user/alpha: Share code for TARGET_NR_sigaction

Browse source 
There's no longer a difference between the alpha code and
the generic code.

There is a type difference in target_old_sigaction.sa_flags,
which can be resolved with a very much smaller ifdef, which
allows us to finish sharing the target_sigaction definition.
