igb: increase timeout for ethtool offline self-test

On several machines with i350 adapters the ethtool offline self-test sometimes
fails. This happens because link auto negotiation may take longer than the
timeout of 4 seconds. Increasing the timeout by 1 seconds resolves the issue.

Output from a failing i350 offline self-test:
while [ 1 ]; do ethtool -t eth2 offline; done
The test result is PASS
The test extra info:
Register test  (offline)         0
Eeprom test    (offline)         0
Interrupt test (offline)         0
Loopback test  (offline)         0
Link test   (on/offline)         0

The test result is FAIL
The test extra info:
