selftests: net: tsn_lib: allow running ptp4l on multiple interfaces
Switch ports will want to act as Boundary Clocks, which are configured using ptp4l by specifying the "-i" argument multiple times. Since we track a log file and a pid file for each ptp4l instance, and we want to be compatible with the existing single-port callers of ptp4l_start and ptp4l_stop, pass the interface list as a single string of space-separated values. Based on this, we create a label for each ptp4l instance, where the spaces are replaced with underscores (ptp4l_start "eth0 eth1" generates "ptp4l_pid_eth0_eth1").
