typeset: print_value(): save/restore last_table

Browse source 
This fix comes via an OpenSUSE patch but also exists in 93v- beta.
https://build.opensuse.org/package/view_file/shells/ksh/ksh93-typedef.dif
(only the printvalue() diff was still applicable to 93u+m;
the setall() fix was done differently and better in a2f13c19)
