[PATCH v13 4/5] bugreport: add uname info

[Emily Shaffer <emilyshaffer@google.com>]

The contents of uname() can give us some insight into what sort of
system the user is running on, and help us replicate their setup if need
be. The domainname field is not guaranteed to be available, so don't
collect it.
