bug 1495798 - shut down sccache server in mozharness after all build steps. r=firefox-build-system-reviewers,gps In builds that use sccache, the sccache server would be shut down at the end of the build step in client.mk. Unfortunately in rusttest builds the check step winds up compiling more Rust code which restarts the sccache server but without the proper configuration. This patch moves sccache shutdown to a post-script step in mozharness so that the server will stay running through the check step.
