Update auto-value to version 1.4.1.

I built these jars locally from the "auto" subdirecories of the
sources from [1], using maven 3.
Based on the version name, those should exactly equal the sources
browsable at [2], but this was not independently verified.

The commands used to build the .jars were:
 - For auto-value-1.4.1-sources.jar:  mvn source:jar
 - For auto-value-1.4.1.jar:          mvn install

auto-value-1.4.1.jar.txt is a copy of [3].
