edje epp - fix gcc warning about possible unused var usage

gcc now is complaining about out ancient cpp code possibly using
newlines as undefined. this should keep this warning quiet - there
isnt a real performance issue here.

bin/edje/epp/cpplib.c: In function ‘cpp_get_token’:
bin/edje/epp/cpplib.c:4602:15: warning: ‘newlines’ may be used
uninitialized in this function [-Wmaybe-uninitialized]
       else if (newlines > 0)

@fix
