file_lock: Add fallback directory

This adds a fallback directory in case SYSTEM_LOCKFILE_DIR is
unavailable. Since this is a band-aid meant to help older systems
auto-update, the fallback path is hardcoded to "/tmp" as to avoid
polluting the overall lockfile API.

BUG=chromium:616620
BRANCH=none
TEST=Tested on veyron_jaq by removing /run/lock and seeing
mosys, flashrom, and ectool run successfully with
firmware_utility_lock in /tmp.
