Fix single quote in cookie value breaking curl output

[eyupcanakman]

Cookie values containing single quotes produced broken curl commands because the value was wrapped with naive single quotes.

Use the existing encode_shell_string function for the --cookie argument, which switches to $'...' quoting when needed.

Fixes #4557
