Bug#905264: im-config: incorrect if syntax prevents login

[Drew Parsons <dparsons@debian.org>]

Package: im-config
Version: 0.36-1
Severity: critical
Justification: breaks unrelated software

im-config currently generates an error at login:
  /usr/lib/gdm3/gdm-x-session[6333]: /etc/gdm3/Xsession: 59: /usr/share/im-config/data/21_ibus.rc: Syntax error: "fi" unexpected (expecting "then")

This prevents login (when using gdm3).

The fix is trivial: add the semicolon in 21_ibus.rc.
