9e622d6bea0202e9fe267955362c01918562c09b in ubuntu_btrfs_kernel_fixes timeouted on B/C P9

[Po-Hsu Lin]

This test will timeout on our P9 node "baltar" (it's the most time-consuming job)

A manual run shows that the sysbench command in this test will take about 2 hours to complete:

# sysbench --num-threads=1 --test=fileio --file-num=81920 --file-total-size=80M --file-block-size=1K --file-io-mode=sync --file-test-mode=seqwr prepare
...
...
...

Creating file test_file.81919
83886080 bytes written in 7231.40 seconds (0.01 MiB/sec).
#

And our timeout threshold is exactly 2 hours. An easy fix for this is to bump the threshold.
But it's weird that this test only fail on Bionic 4.15.

Here is the performance matrix for how long does it take for this test to execute:
* Bionic 4.18 - 90 minutes
* Disco 5.0 - 99 minutes
