lldb: Linux: empty Ptrace.h pollyfill (#218038)
As the comment in sources alludes to:
> System includes - They have to be included after framework includes
because
> they define some macros which collide with variable names in other
modules.
Mixing includes of sys/ptrace.h with other headers can lead to conflicts
that cause i386 lldb-server builds to fail when build against bionic.
Prepare to remove this header outright.
