bug#46491: [feature/pgtk] Unused macro warning in image.c without ImageMagick

[Basil L. Contovounesios]

X-Debbugs-Cc: Yuuki Harano <masm+emacs@masm11.me>
Severity: minor
Tags: patch

The following is the only build warning I currently get on feature/pgtk:

  image.c:110: warning: macro "DONT_CREATE_TRANSFORMED_IMAGEMAGICK_IMAGE"
    is not used [-Wunused-macros]
    110 | # define DONT_CREATE_TRANSFORMED_IMAGEMAGICK_IMAGE

Is the attached patch the right fix?  If so, I can push it after adding
the bug#number to it.

Thanks,
