files: with --rectrict, prevent invoking the browser and toggling backups

Browse Source 
Prevent also the toggling of Append and Prepend.  All four functions
should not be available in restricted mode, and are absent from the
WriteOut menu in that mode, but using {browser}, {backup}, {append}
or {prepend} in a string bind allowed to bypass the menu checks.

This fixes https://savannah.gnu.org/bugs/?65819.

Problem existed since version 7.0, since braced function names
were introduced.
