Summary

This change adds the necessary glue to translate Linux scheduler policy
and priority from FreeBSD so this information is available to Linux
applications.

This unbreaks using the Linux version of Chromium on FreeBSD.

This change was originally submitted via [freebsd/freebsd-src#2370][github-pr].
