Add a new selftest to verify netconsole module loading with command line arguments. This test exercises the init_netconsole() path and validates proper parsing of the netconsole= parameter format. The test: - Loads netconsole module with cmdline configuration instead of dynamic reconfiguration - Validates message transmission through the configured target - Adds helper functions for cmdline string generation and module validation This complements existing netconsole selftests by covering the module initialization code path that processes boot-time parameters. This test is useful to test issues like the one described in [1].
