pdftoepdf.w: work around generation removing too much whitespace

The error observed with Clang 3.9.1 (x86_64-apple-darwin16.6.0) is

texlive-20170524-source/texk/web2c/luatexdir/image/pdftoepdf.w:74:34:
error: 
      invalid suffix on literal; C++11 requires a space between literal and

                                 ^

Adding newlines does the trick, because the generation keeps them, and
the compiler as suck sees whitespace between the literal and identifier.
This is of course a kludge, the original code is correct, the generator
should probably be fixed.
