[PATCH v2] tools headers: Skip arm64 cputype.h check

[PATCH v2] tools headers: Skip arm64 cputype.h check

[Leo Yan]

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 when teaching tools about new CPUs.

Changes in v2:
- Explicitly states that update cputype.h for new CPUs (Mark).
- Link to v1: https://lore.kernel.org/r/20260316-tools_remove_sync_cputype-h-v1-1-9f0dc5931f09@arm.com

Thanks, applied yesterday to perf-tools, for v7.0.
