JDK-8332248 - (fc) java/nio/channels/FileChannel/BlockDeviceSize.java failed with RuntimeException
Description
JDK-8054029 added a test for block device sizes, which tests `/dev/sda`. There is a high chance that modern computers moved to NVMe, and so the "default" device name would be e.g. `/dev/nvme0n1` or some such.

The test needs to poll more devices trying to find the block device on the system.
