The writable ID register test depends on the latest system register
definitions, which cannot be trivially added to tools. In order to keep
a single copy of sysreg gunk in tools all users (KVM selftests, perf)
need to be updated to generate headers at build time.

Tested arm64 and x86 builds of both KVM selftests and perf tool.

v1 -> v2:
 - Use the sysreg definition generation script instead of copying the
   output (broonie)
 - Use a common Makefile for both KVM selftests as well as perf
 - Include the KVM selftest responsible for the change
