monogame-patcher: Improve values for replace-call

Using an IEnumerable for the search and replace arguments isn't really a
very good idea, because it makes command line usage very annoying and
messes up the usage description.

I originally made this an IEnumerable because I wanted to have a way to
specify multiple replacements, but we can simply run the patcher twice
or more times.
