Our header guards commonly end in _H.  Normalize the exceptions.

Done with scripts/clean-header-guards.pl.

> Can we use HVF_VMCS_H?

Yes, but not in this patch.  This one merely strips leading and trailing
underscores, and normalizes to trailing _H.  The previous patch renames
the header guards that don't match the filename.  VMCS_H matches, so a
rename to HVF_VMCS_H doesn't fit there, either.

Additional patches could do local header guard normalization, e.g. for i
in target/i386/hvf/*.h, rename $i's header guard to HVF_${i^^}.
