[ARM] Replace extramask with a full copy of the sigmask
There's not much point in splitting the sigmask between two different locations, so copy it entirely into a proper sigset_t. This will eventually allow rt_sigframe and sigframe to share more code. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
