stlink: default dapdirect to SWD instead of JTAG 

When the transport is not specified, OpenOCD uses the first listed
by the selected adapter driver.
The old HLA driver for stlink lists SWD as first. The new driver
dapdirect instead lists JTAG, making more difficult a fallback to
HLA when dapdirect is not available due to old stlink FW.
Plus, in case of JTAG wiring, SWD is still possible, while the
opposite is not.

Reorder the list of transports to grant the default to SWD.
