OpenBSD: Add support for missing routine memmove() in kernel.

OpenBSD does not have the memmove() routine available to dynamically
loaded modules in its kernel. It exists but is not exported so it
winds up "mia" on dynamic load of the kernel module. It's needed for
the Heimdal code that's been added into OpenAFS. This patch deals
with this issue by creating an inline version in the OS-specific
param.h file.

Note that this issue does not seem to exist in the amd64 version of
OpenBSD so (at least for now) tis fix is only applied to the i386
version of the header files.
