Sandbox filesystem creation slow on OSX

[DavidZbarsky-at]

Description of the bug:

When using rules_js for JS projects, NPM packages are modeled as TreeArtifacts. This helps with analysis phase performance, but actions still have high overhead because TreeArtifacts are expanded, even with --noenable_runfiles.
