Remove old benchmark tools.

Remove the old benchmark-tools directory, including
imports in the WORKSPACE file and associated bazel rules.

The new Golang benchmark-tools can be found at //test/benchmarks
and it is functionally equivalent, excepting syscall_test
which can be found in //test/perf/linux.
