Radostin Stoyanov 4c1ee3e227 test/other: Resolve Py3 compatibility issues
When Python 2 is not installed we assume that /usr/bin/python refers to
version 3 of Python and the executable /usr/bin/python2 does not exist.

This commit also resolves a compatibility issue with Popen where in
Py2 file descriptors will be inherited by the child process and in
Py3 they will be closed by default.
