Upgrade google-http-client and google-http-client-gson. (bazelbuild#1…

…6745)

In bazelbuild#15176 we upgraded google-auth-library-oauth2-http to 1.6.0, but didn't
upgrade its dependencies accordingly; Maven claims 1.41.4 is needed [1].
In turn, a new transitive dependency on opencensus-contrib-http-util 0.31.0
also becomes necessary [2].

Fixes bazelbuild#15639.

[2] https://mvnrepository.com/artifact/com.google.http-client/google-http-client/1.41.4

Partial commit for third_party/*, see bazelbuild#16082.
