cairo-trace: Fix duplicated surface push on similar-image

The current code results in trace lines with the source surface being
pushed on the stack two times instead of one:

s1 s1 //ARGB32 48 48 similar-image % s2

Instead of:

s1 //ARGB32 48 48 similar-image % s2

This greatly confuses later commands when the script was replayed,
causing traces for trivial GTK3 programs to be unplayable, usually
yielding the following error:
"invalid value (typically too big) for the size of the input (surface, pattern, etc.)"

Drop the duplicated entry from the trace line printed by the
cairo_surface_create_similar_image() override.
