When realpath is given a NULL argument, it returns a buffer allocated
with malloc containing the path. Update getrealpath function to rely
on this behaviour instead of using PATH_MAX.
While making this change, verify that callers of getrealpath
responsibly free the returned buffer once they no longer have use for
it.
