stlink: fix printed version for new STM8 nucleo board 

The ST-LINK/V2.1 embedded in the new nucleo boards for STM8 does
not follow the normal versioning rules, and puts mass-storage and
swim version in the field normally used respectively for jtag and
mass-storage version.

Apply the check suggested by STMicroelectronics to discriminate
the two cases and print the correct version.
