asm-generic: remove ptrace.h

Browse source 
The asm-generic changes for 5.3 consist of a cleanup series from
 Christoph Hellwig, who explains:
 
 "asm-generic/ptrace.h is a little weird in that it doesn't actually
 implement any functionality, but it provided multiple layers of macros
 that just implement trivial inline functions.  We implement those
 directly in the few architectures and be off with a much simpler
 design."
