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).
