[PATCH v3 1/3] tools include: Grab copies of arm64 dependent unistd.h files

[Kim Phillips <kim.phillips@arm.com>]

Will be used for generating the syscall id/string translation table.

Arm64's unistd.h simply #includes the asm-generic/unistd.h, so,
since we will want to know whether either change, we grab both:

  arch/arm64/include/uapi/asm/unistd.h

and

  include/uapi/asm-generic/unistd.h
