Remove META-INF/*.kotlin_module entries from the AutoValue jar.

We bundle a shaded copy of `kotlinx.metadata.jvm` and related libraries, which we use to inspect Kotlin data classes. The libraries are only called from Java code, which means that `META-INF/kotlinx-metadata-jvm.kotlin_module` and the like serve no purpose, other than to confuse the Kotlin compiler when it sees these entries.

Fixes #1574.

RELNOTES=An "incompatible version" issue with Kotlin compilation has been fixed. See #1574.
