Hi,

DocView seems to do the wrong thing on a Postscript file when there is
support for SVG in Emacs.  I also have "gs" and "mutool" installed.

How to reproduce:
    - emacs -Q
    - C-x C-f "existing-document.ps"
    - C-c C-c -> no images displayed

Looking for pages into the cache with `doc-view-dired-cache', it seems
that DocView has produced PNG content into files with "svg" extension.
Emacs then tries to display SVG images with PNG content and, obviously,
failed.

The following patch fixes the issue for me but maybe there is more than
meets the eye:
