Fix the arm sys_sigreturn(): its argument is a struct ucontext, not a

struct sigframe containing the struct ucontext.

The signal trampoline return code on the other hand DOES have just a
struct sigframe on the stack to work with, so have it get a pointer to
the ucontext out of there to pass along to sys_sigreturn.

In other words, make everything work right whether sys_sigreturn is
invoked from the trampoline or from userland code calling sigreturn(2).
