um: finish conversion to mcontext_t

now we don't mix host and guest signal frame layouts anymore; moreover,
we don't need host's struct sigcontext at all.

um: simplify set_handler()
...
For one thing, we always block the same signals (IRQ ones - IO, WINCH, VTALRM),
so there's no need to pass sa_mask elements in arguments. For another, the
flags depend only on whether it's an IRQ signal or not (we add SA_RESTART
for them).

We used to generate those, but we hadn't done that for a long
time. No need to bother blocking them for signal handlers.
