libvirt: fix python3 compatibility in hook_support.py

By default Popen expects all the streams to be bytes-like objects but,
in the Popen.communicate() function call, the "input" argument is a
string, making the call fail with the error:

qemu hook error: a bytes-like object is required, not 'str'

Fix the error by setting text mode to True in the subprocess creation.

Also fix the "SyntaxWarning: invalid escape sequence '\w'" in the regex
used to match script names.
