ARM: signal: stop using __put_user() for the signal frame

The signal frame is checked with access_ok() once, in get_sigframe(),
and a few of its fields are then written with __put_user(): the ucontext
flags and link, the end marker after the coprocessor state, and the
sigreturn trampoline words.

Use scoped_user_write_access() with unsafe_put_user() where there are
several writes in a row, and put_user() for the two single ones.  ARM
has no user_access_begin(), so the scopes are the same access_ok() and
the same accesses as before.

This is part of getting rid of __get_user() and __put_user() entirely.
