Fix //tools/gn/example on Linux: missing current_os and related vars

The example GN project's BUILDCONIG.gn needs to set {target,current}_{os,cpu)
variables like the Chromium BUILDCONFIG file does. Otherwise some conditionals
don't work like they do in Chromium and the project doesn't link on Linux,
which is needlessly confusing.

To test, `gn gen out' in //tools/gn/example, and then `ninja -C out'.
