repl: use _REPL_ in user-facing text

User-facing error messages should use _REPL_ for the general REPL and
not _repl_ which should be reserved for referring to the module itself,
etc. _REPL_ is an acronym, so it should be capitalized, as it generally
is in documentation in other technologies, and is usually in our own
documentation. This fixes a few inconsistent usages in lib/repl.js.
