Use different label printing strategies for XUL 1.9.2 vs. 1.9.0

r16421 contained a fix for printing in XUL 1.9.2 that appears to have
broken printing in XUL 1.9.0. This change should switch back to the old
style of printing if XUL 1.9.0 is detected, and otherwise uses the 1.9.2
strategy for any other version of XUL.
