jtag: linuxgpiod: use libgpiod v2 API for gpiod_line_request()

Browse Source 
Work in progress. Target is to replace v1 gpiod_line_request()

Define and use dummy functions from v2 for v1:
- gpiod_line_config_new(),
- gpiod_line_config_free(),

Not yet used:
- gpiod_line_config_add_line_settings(),
- gpiod_chip_request_lines().
