Add -DUPOWER_ENABLE_DEPRECATED to makefile (Bug 10931)

Xfpm requires the UPOWER_ENABLE_DEPRECATED symbol to be present
for suspend/hibernate to still work on upower versions 0.9.8 thru
0.9.23. Adding it for later versions of upower won't do anything,
so there's no harm in just adding it.
Thanks to Samuli Suominen for reporting and finding the correct
fix for this.
