Windows builds: locale.bindtextdomain() not available

[Kreijstal]

essentially same as innstereo/innstereo#46

when trying to compile in msys2:

# ./conjure
Traceback (most recent call last):
  File "C:/conjure/build/conjure/conjure", line 35, in <module>
    locale.bindtextdomain('conjure', localedir)
    ^^^^^^^^^^^^^^^^^^^^^
AttributeError: module 'locale' has no attribute 'bindtextdomain'

we could try using a try catch here
