benchmark: add common.binding()

Recently, process.binding() was replaced with internalBinding(). However, internalBinding() is not available on older builds of Node, which are often used for benchmarking purposes. This commit adds a common.binding() to the benchmarks to work around the issue. Hopefully, this can be removed in the not too distant future.
