parisc: remove unused compat_rt_sigframe.h header

Nothing uses compat_rt_sigframe.h anymore. Commit
f671c45d ("[PARISC] Arch-specific compat
signals") removed all includes of that header. It also basically copied
that entire header verbatim into signal32.h. It seems it was just
forgotten to also remove compat_rt_sigframe.h from the tree. Remove that
header now.

* The 32-bit ABI wants at least 48 bytes for a function call frame:
* 16 bytes for arg0-arg3, and 32 bytes for magic (the only part of
* which Linux/parisc uses is sp-20 for the saved return pointer...)
* Then, the stack pointer must be rounded to a cache line (64 bytes).
