dedekind_sum.patch

Patch tests of arb-2.5 to be compatible with flint-2.4.4

Arb's testsuite, src/acb_modular/test/t-epsilon_arg.c, calls
fmpq_dedekind_sum. However, this function does not exist in
flint-2.4.4.

fmpq_dedekind_sum was introduced in
https://github.com/wbhart/flint2/commit/64f656fb8db591ea11db606c7905de9f47b05e84
and arith_dedekind_sum is now an alias to fmpq_dedekind_sum.

So I patch src/acb_modular/test/t-epsilon_arg.c to call
arith_dedekind_sum instead of fmpq_dedekind_sum.
