[COMMIT] Let inf-ptrace.c inherit more stuff from inf-child.c

[Mark Kettenis <kettenis at gnu dot org>]

Currently, in inf-ptrace.c, we have many dummy implementations that
are identical to the ones in inf-child.c.  Andrew update some of them
in inf-child.c for a change in some of the function signatures, but
forgot about the copies in inf-ptrace.c.  It's clear these copies form
an unnecessary maintenance burden, so this patch simply removes them.
Fixes the warnings I got when compiling inf-ptrace.c on OpenBSD and
FreeBSD.

Committed,

Mark
