util: make buffer readonly

There is no use of writable buffers anywhere in the code, and this helps us
make sure we don't get into unsound territory when sharing memory with Rust.

This `toreadonly` method was not available in Python 3.6, but we dropped the
support for it earlier that week, so no need for any compatibility code.

{
    // Enforcing
    "eqeqeq"        : true,     // true: Require triple equals (===) for comparison
    "forin"         : true,     // true: Require filtering for..in loops with obj.hasOwnProperty()
    "freeze"        : true,     // true: prohibits overwriting prototypes of native objects such as Array, Date etc.
    "nonbsp"        : true,     // true: Prohibit "non-breaking whitespace" characters.
    "undef"         : true,     // true: Require all non-global variables to be declared (prevents global leaks)

    // Environments
    "browser"       : true      // Web Browser (window, document, etc)
