CMake/Linux: Fix Brotli library finding on standard distros.

Brotli seems to add a custom postfix to its static libraries by default,
but in Debian at least libraries are just named the same for both shared
and static versions, as usual.

So add standard name after static-specific ones.

Follow-up to rB4c617c06e9cb and rBa000de7c2a4d.
