commands: setenv: allow use with hush shell
setenv was so far restricted to the simple shell, because with hush,
users could just do dev.var=VAL for setting variables in the
environment. The hush syntax doesn't allow for setting all kinds of
environment variables though, e.g.
5c00a000.tamp@5c00a000:reboot-mode.of.param
can't be set with hush, because of the special characters. It could
still be read by using the ${variable} syntax though.
Allow setting these variables by making the setenv command generally
available. The default is chosen to be 'y', because the command is
deemed small and useful enough to have it there by default.
