 fix build for non-linux platforms

 remove two calls to free with an array as the argument
 This is bad code, invoking undefined behaviour if executed.  I suspect it
 never actually will be, as by default "new" in C++ throws an exception if
 it fails, and I don't see anything in the rlplot code to change that.

 The issue was spotted by a new GCC warning.
