scripts/common: set special name to test partitions

SPDK test script can fail during any point of the
execution. To keep using the same devices
between test runs in CI, those devices have to
be cleaned between runs.

To select device for tests or to clean before tests,
the partition table and lack of mount points is used.
SPDK GPT partitions were always considered not in use.
Meanwhile Linux GPT were not, even if lacking a mount
point.

Some of the SPDK tests create Linux GPT partitions,
which might remain after a test run.

Linux GPT partitions created during tests now contain
"SPDK_TEST" as part of their partition name.
This allows marking such block devices as 'not in use',
to be cleaned and used in further SPDK test.

fixes #2345
