[Android WebView] Relax license parsing for BSD

This adds "2-clause BSD" and "3-clause BSD" to whitelisted licenses.
This is only a wording issue, since "BSD 2-clause" and "BSD 3-clause"
are already whitelisted.

This makes third_party/mach_override pass webview license check, even
though that particular library is not used by webview.
