Bug 1582241 - Increase ccov browser-chrome max-run-time; r=marco

Increase max-run-time for linux and windows ccov browser-chrome tasks to avoid
frequent task timeouts. (linux platform name was incorrect in existing configuration).
I would prefer to see shorter max-run-time but there may be no alternative for
these tasks.
