Release builds are unable to build using workers

When attempting to perform a release build, the build fails with the following error log:

ERROR: /usr/local/google/home/amysorto/components/src/material/datepicker/BUILD.bazel:90:12: SassCompiler src/material/datepicker/date-range-input.css failed: Worker process did not return a WorkResponse:

We have temporarily worked around this by forcing local spawn strategy.
