build_recipe: patch lightstep in the meantime (#1431)

Fixes: #1387

While we wait for
https://github.com/lightstep/lightstep-tracer-cpp/pull/51
and then further, for an update to newer lightstep, this fetches an
absolute path to a patch that lets our lightstep build work on newer gcc
versions (>= 7).
