set: Use env_var_t::flags_for() to see if it's read-only

Browse Source 
env_var_t::read_only() is basically broken.

It doesn't work for $PWD, as best as I can tell no variable is
read-only except for a hardcoded list of some of the electric ones.

So we should probably remove the entire read_only and
setting_read_only mechanism.
