Some definitions in the arm64 kernel's cputype.h are kernel specific and
cause perf build failures when the header is synced into tools.

Stop checking arm64's cputype.h.  In the future, the header in tools
will be updated manually as needed.

I think it might be worth stating explicitly that we only need to update
this header when teaching the perf tool about new CPUs, but with or
without that wording:
