Remove double quoting of bazel_config

The bazel_config variable can either contain a java-specific config
or the empty string. When the bazel_config is empty, it should not
pass anything to the bazel command line, otherwise it would be
interpreted as an additional empty parameter and failing the build.

The builds for Gerrit v3.12 were failing because of this extra
empty bazel_config, therefore needed manual adjustments before this
change.
