GDB vcl.py: actually return a string in to_string

... and hopefully make it python2.7 compatible... definitly a
"brown paperbag" fix... well it did work locally ;-)

I just noticed, because Jenkins spilled some errors from GDB on
hang with:

Traceback (most recent call last):
File "/.../instdir/program/libvcllo.so-gdb.py", line 23, in <module>
module = importlib.import_module('libreoffice.' + mod)
File "/.../python2.7/importlib/__init__.py", line 37, in import_module
__import__(name)
File "/.../solenv/gdb/libreoffice/vcl.py", line 101
print('STACK', end =", ")
