Allow always logging tofu detection

Browse Source 
This commit allows to log tofu detection always,
even if the rest of the webfonts library is not loaded.

By default this is disabled.

To enable it, set the variable $wgULSTofuLoggingChance
to a number between 0 and 100, indicating the chance of it
getting logged. The idea of the lottery is that even a partial
sample can be useful.
