Fix inferior octave single-quote font lock

* lisp/progmodes/octave.el (octave-mode-syntax-table): Fix
fontification of single quotes in inferior octave mode (bug#25517).

It looks like the problem is that octave-mode-syntax-table sets single
quotes as punctuation even though GNU Octave's manual says single quotes
are string syntax [1].
