Fix an out-of-bounds memory access in xc_ptrace.c.

Currently, Xen always copies the entire 512 byte extended
FPU state (fxsave) even if only the "regular" FPU state was
requested.

This breaks since the memory buffer allocated in
linux-xen-low.c:regsets_fetch_inferior_registers() is only large
enough to hold the "plain" FPU registers.
