[ARM] Remove rt_sigframe puc and pinfo pointers
These two members appear to be surplus to requirements. Discussing
this issue with glibc folk:

| We can kill them. I checked with Phil B. about them last week, and he
| didn't remember any reason they still needed to be there. And nothing
| should know where they are on the stack. Unfortunately, doing this
| will upset GDB, which knows that the saved registers are 0x88 bytes
| above the stack pointer on entrance to an rt signal trampoline; but,
| since puc and pinfo are quite recognizable, I can adapt GDB to support
| the new layout if you want to remove them.
So remove them.
