fix: Restore STDERR in pngtest.c
In "test: Add consistency checks for the PNG_LIBPNG_VER* number" [0] the
`STDERR` macro was moved from outside an `ifdef` to inside an `ifdef`.
This broke the code in the `else` of this `ifdef` which also uses the
`STDERR` macro. Move `STDERR` back to where it was to avoid compile
errors in the `else` case.
