Bump version of stout-eventuals, fix local build

Update stout-eventuals in light of recent changes, in particular the
inclusion of Post and Get that relies on curl. The inclusion of curl
introduces two new repo dependencies included in this commit.

As outlined in issue #17, building `:grpc` locally using `gcc` is
currently broken by `.bazelrc`. This commit works around it by removing
the offending compiler flags, allowing the library to be built locally.
This is not a fix for the issue: we want those compiler flags in there,
conditionally.
