scripts: Make cros_generate_stacks_bvt user-friendlier.

Browse Source 
This adds support for using debug tarballs located on the
local machine instead of only ones on remote servers.  (If
the first argument is a local file, we use it; otherwise, we
try to download it.)

It also makes us download the (tiny) minidumps before the
(huge) tarball so we can bail out quickly if the minidump
URL is wrong.

BUG=chromium-os:19565
TEST=manual: ran it successfully with both local and remote tarballs and checked that it fails early when given an invalid minidump path
