SMT2 parser: Do not add non-linear symbols for linear Int arith logics. (#5787)
This enables more strict handling of operators div, mod and abs
for Integer arithmetic logics.
More strict handling for '/' for Real arithmetic logics is more involved
and should be done in the parser -- instead at solving time, like is
currently done for checking that the application * is in the linear
fragment. The latter should be checked in the parser, too.
This is postponed to a later PR.
