Fix Wbitwise-instead-of-logical warnings

`a && b` only evaluates b if a is true. `a & b` always evaluates
both a and b. If a and b are of type bool, `&&` is usually what you
want, so clang now warns on `&` when both arguments are of type bool.
In the one case where this fires in webrtc, it isn't important if we
evaluate both branches, so I went with `&&`.
