[osx] make profiler unittest pass

Browse Source 
somehow VerifyIdentical tests fail for some formatting details. But
since it tests --raw feature of our deprecated perl pprof
implementation, which we don't intend supporting anyways, we drop this
test.

There is some details about how wc -l returns stuff and how zsh uses
it to compare to 3. So we now explicitly strip whitespace and it
works.
