[PATCH v1] perf MANIFEST: Add gen-sysreg for ARM SPE

[Ian Rogers <irogers@google.com>]

The necessary files for generating sysreg-defs.h need adding to the
perf tool MANIFEST that lists the files for packaging the perf tool
source code. Fix for the following:

```
$ make perf-tar-src-pkg
$ tar xvf perf-6.7.0-rc2.tar
$ cd perf-6.7.0-rc2
$ make -C tools/perf
...
  PERF_VERSION = 6.7.rc2.gc2d5304e6c64
make[3]: *** No rule to make target 'perf-6.7.0-rc2/arch/arm64/tools/gen-sysreg.awk', needed by 'perf-6.7.0-rc2/tools/arch/arm64/include/generated/asm/sysreg-defs.h'.  Stop.
make[2]: *** [Makefile.perf:456: arm64-sysreg-defs] Error 2
make[2]: *** Waiting for unfinished jobs....
make[1]: *** [Makefile.perf:242: sub-make] Error 2
make: *** [Makefile:70: all] Error 2
make: Leaving directory 'perf-6.7.0-rc2/tools/perf'
...
```

Note: the breakage is in Linus' tree and perf-tools, not yet in perf-tools-next.
