To specify the serial number, JLink expects either one argument
('--dev-id=xxx') or two (e.g. '--dev-id' 'xxx'), but it can not deal
with a single one that is '--dev-id xxx'.
The problem has been introduced (or just made visible?) by commit
5ee4284320 (twister: runner: j-link: use
dev-id instead of SelectEmuBySN) in PR #76931.
How to reproduce:
1. Create a HW configuration map, e.g.:
```
$ cat zephyr-hw-map-nrf52840dk-1.yml
- connected: true
id: '683517317'
platform: nrf52840dk/nrf52840
product: nRF52840 DK 1
runner: jlink
serial: /dev/ttyACM-nrf-dk-1
```
2. Run test `logging.dictionary` with Twister:
```
$ west twister --platform nrf52840dk/nrf52840 --device-testing \
--hardware-map zephyr-hw-map-nrf52840dk-1.yml -s logging.dictionary
```
3. The build will fail, and the `twister_harness.log` contains:
```
10:21:24.375:DEBUG:twister_harness.device.factory: Get device type
"hardware"
10:21:24.375:DEBUG:twister_harness.device.hardware_adapter: Opening

10:21:24.592:DEBUG:twister_harness.device.hardware_adapter: Closed

```
(note the '--dev-id 683517317' part)
4. Running the stated `west flash` command shows the following error
message:
```
-- west flash: using runner jlink
FATAL ERROR: runner jlink received unknown arguments: ['--dev-id
683517317']
```
