parisc: Disable CONFIG_HAVE_ARCH_TRACEHOOK

> FYI, this commit broke tip:master on PARISC (other architectures are fine):
>
>  kernel/built-in.o: In function `ptrace_request':
>  (.text.ptrace_request+0x2cc): undefined reference to `task_user_regset_view'

This means that parisc failed to meet the documented requirements for
setting CONFIG_HAVE_ARCH_TRACEHOOK, but set it anyway.  If arch folks don't
follow the specs, it defeats the whole purpose of having clear statements
of requirements for arch code.

Until parisc finishes up its requirements, disable CONFIG_HAVE_ARCH_TRACEHOOK.
