Improve help text for (lldb) target symbols add

[amccarth]

Summary

There were some missing words and awkward syntax. I think this is clearer.

Looks good, for the --shlib option I would get rid of the "full path or base name" language and just say "name", my two cents.

I agree just "name" seems fine. Done.

This is low risk and it did get positive comments from one non-reviewer, so I'm going to land this.
