Scripts starting with "#!/usr/bin/emacs -x" do not function with PGTK Emacs.

Instead of evaluating the file contents, Emacs creates a new instance
and opens a frame, echos a warning about "-x" being an unknown option in
the minibuffer. This seems to suggest that the "-x" option is not being
recognized at all.

The statement that parses this specific parameter seems to be inside
of a conditionally compiled block of code that toggles based on the
macro HAVE_X_WINDOWS (#ifdef HAVE_X_WINDOWS).

My current build of Emacs uses the PGTK, and non-PGTK builds appear to
function correctly when used with the "-x" option.

This option doesn't seem to be related to x11 in any way as far as I can
tell, so I have moved it to the location where the "--script" option is
parsed, and then decrement skip_args by 2 instead of 1 which is also what
"--script" does.

These changes cause the "-x" option to function correctly, but I am not
experienced in C or with the C parts of Emacs, so this may not be the
correct solution!
