motd breaks pickRemoteNativeProcess

Nobody has claimed this yet.

Issue Type: Bug

I'm running vscode on windows connected to a linux wsl2 VM attempting to attach-debug another remote linux machine.

launch.json:

		{
			"name": "(gdb) Pipe Attach",
			"type": "cppdbg",
			"request": "attach",
			"program": "/my/to/app",
			"processId": "${command:pickRemoteProcess}",
			"pipeTransport": {
				"debuggerPath": "/opt/rh/devtoolset-9/root/usr/bin/gdb",
				"pipeProgram": "/usr/bin/ssh",
				"pipeArgs": [
					"user@remote-host"
				]
			},
			"MIMode": "gdb",
			"miDebuggerPath": "/opt/rh/devtoolset-9/root/usr/bin/gdb"
		},

when i start debugging the remote-attach window shows:

Linux
      aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa 
    1 systemd                                           /usr/lib/systemd/systemd --switched-root --system --deserialize 21
...

*******
** blah blah motd blah

and the Remote Extension Host log shows:

[2021-04-15 16:20:07.334] [exthost] [error] Error:

turning off the motd is not an option.

Start by tracing extension.pickRemoteNativeProcess and the reported main.js location around line 769, then reproduce the command with the shown pipeTransport and MOTD output. Verify how the remote process list is parsed when MOTD text is present; done means selecting a remote process succeeds without requiring MOTD changes.
