Remove startup JVM version check

This was added during the JDK 7->8 transition to improve the diagnostic
when an older-than-supported host_javabase was used. The version number
handling doesn't work with JDK 9 (see [1]), and using Bazel binaries
with a bundled host_javabase avoid the error entirely so the message
is less important.
