Test "--device-read-bps" "--device-write-bps" will fail. The root
cause is that GetList helper return empty as its local variable
initialized to zero size.
This patch fix it by setting the related slice size to non-zero.

Commit a77f2450c70312f8c26877a18bfe2baa44d4abb9 switched `docker run`
to use the `pflags` package. Due to this change, the usage output for
the `--blkio-weight-device` and `--device-*` flags changed and now
showed `weighted-device`, and `throttled-device` as value type. As a
result, the output of `docker run --help` became a lot wider.
This patch changes the output to show `list` instead, which is
consistent with other options that allow to be set multiple times.
Output before this change;

Options:
--blkio-weight uint16 Block IO (relative weight), between 10 and 1000, or 0 to disable (default 0)
--blkio-weight-device weighted-device Block IO weight (relative device weight) (default [])
--device list Add a host device to the container (default [])
--device-read-bps throttled-device Limit read rate (bytes per second) from a device (default [])

… or could be in `opts` package. Having `runconfig/opts` and `opts`
doesn't really make sense and make it difficult to know where to put
some code.
