KVM: ia64: fix GVMM module including position-dependent objects

The GVMM module is position independent since it is relocated to the guest
address space.

Commit ea696f9c ("ia64 kvm fixes for O=... builds") broke this by linking
GVMM with non-PIC objects.

Fix by creating two files: memset.S and memcpy.S which just include the files
under arch/ia64/lib/{memset.S, memcpy.S} respectively.

[akpm: don't delete files which we need]
