tools arch s390: Do not include header files from the kernel sources
Long ago we decided to be verbotten including files in the kernel git
sources from tools/ living source code, to avoid disturbing kernel
development (and perf's and other tools/) when, say, a kernel hacker
adds something, tests everything but tools/ and have tools/ build
broken.
This got broken recently by s/390, fix it by copying
arch/s390/include/uapi/asm/perf_regs.h to tools/arch/s390/include/uapi/asm/,
making this one be used by means of <asm/perf_regs.h> and updating
tools/perf/check_headers.sh to make sure we are notified when the
original changes, so that we can check if anything is needed on the
tooling side.
This would have been caught by the 'tarkpg' test entry in:
$ make -C tools/perf build-test
When run on a s/390 build system or container.
