[l10n] Treat language as case-insensitive

Browse source 
See "Case-insensitive language comparisons per RFC 4646"
https://github.com/fabi1cazenave/webL10n/pull/51

Removed the "patch" in compatibility.js and fixed the bug in webL10n,
because the logic belongs to webL10n instead of PDF.js.
The immediate motivation for this patch is that Chrome 40 converts
navigator.language to lower case: https://crbug.com/454331
