Some places were including event.h just to get 'struct perf_sample',
move it to a separate place so that we speed up a bit the build.

This is currently working due to extra include paths in the build.
Before:
$ cd tools/perf/arch/arm64/util
$ ls -la ../../util/unwind-libdw.h
ls: cannot access '../../util/unwind-libdw.h': No such file or directory
After:
$ ls -la ../../../util/unwind-libdw.h
-rw-r----- 1 irogers irogers 553 Apr 17 14:31 ../../../util/unwind-libdw.h

Based on prior work:
https://lkml.org/lkml/2014/5/6/395
and on how other arches add libdw unwind support. Includes support for
running the unwind test, e.g., on a system with only elfutils' libdw
0.170, the test now runs, and successfully:
$ ./perf test unwind
56: Test dwarf unwind : Ok
