littlefs: Increased test timeout to 4 minutes

Unfortunately there are several issues colluding to force the timeout
this high.

1. The tests push littlefs to the limits of how many errors it can
handle before failing. As a side effect this causes a massive amount
of debug/warn/error logging about the situation.

2. The logging can't be turned off for specific tests. Note: This might
change with the introduction of test-configs.

3. Logging is fixed to a baud rate of 9600. Previous testing was carried
out with a baud rate of 115200, which is the reason for the original
timeout.
