symbolize.py: Python < 3.7 compatibility

The documentation for the Python 3 subprocess module [1] has the
following note related to the Popen() constructor:

 Changed in version 3.7: Added the text parameter, as a more
 understandable alias of universal_newlines.

In order to avoid a runtime error with versions of Python prior to 3.7,
replace the 'text' parameter with 'universal_newlines'.
