Subject: [PATCH] tests: sandboxing

The slowness of bazel-zig-cc comes from setup and teardown of sandbox
directories[1]. Turning on `experimental_reuse_sandbox_directories`
speeds it up significantly.

Depending on how the tests with this go in the next few days, I will add
this recommendation to README.

This has been marked as safe to use and no longer experimental as of
Bazel master[2].
