[PATCH blktests] nvme/039: adjust to util-linux v2.40 dmesg format change

[Shin'ichiro Kawasaki]

Since util-linux version 2.40, dmesg supports "caller ID". When Linux
kernel supports CONFIG_PRINTK_CALLER, dmesg adds thread ID or CPU ID
with parenthesis such as [    T123] or [     C16] to each message. This
made the dmesg string check of the test case nvme/039 fail. Fix this by
filtering out the added caller ID field.
