Fix task priorities for console and hostcmd tasks
The console task should be higher priority than the host command task,
since that allows debugging problems with host commands.
The keyboard scanning task should be higher priority than both of
them, since it's extremely latency-sensitive. As currently written,
long-running host commands such as I2C passthru can interfere with
keyboard scanning.
BUG=chrome-os-partner:22681
BRANCH=none (potentially affects pit, but apparently not noticeably)
TEST=type bursts of 6-8 characters quickly while doing a flash update
of the EC; should not drop characters.
