Subject: [PATCH] tools/impact: Tweak the uname call

It turns out that OS X doesn't support long options for uname and it
doesn't support -o/--operating-system at all. Let's tweak uname's
options into something POSIX-compatible which still gives reasonable
results.

The new "uname -mrs" call results in the following:

  OS               uname -mrs
  -----------------------------------------------
  OS X Mavericks   Darwin 15.2.0 x86_64
  Ubuntu 14.04     Linux 3.13.0-32-generic x86_64
