perf tools: Fix dependency for version file creation

The version generated by perf may not be correct by just changing the
head commit, like this:

  $ git log --pretty=format:"%H" -n 1
  b5d9d4708a24ac1889a30e9aedf8af8d73102139
  $ perf -v
  perf version 5.16.gb5d9d4708a24
  $ git reset --hard HEAD^
  HEAD is now at 629f520b265f
  $ make
  ...
  $ ./perf -v
  perf version 5.16.gb5d9d4708a24

The dependency to building PERF-VERSION-FILE should also include ORIG_HEAD,
as this changes when changing the head commit (while HEAD does not).
