Fix prettification of \phi, \varphi, and \varsigma

* lisp/textmodes/tex-mode.el (tex--prettify-symbols-alist): Fix
  prettification of \phi, \varphi, and \varsigma.

Concretely, \phi's symbol was actually varphi, \varphi was missing, and
\varsigma was commented out with a FIXME that it was reversed with
\sigma which it was not.
