Test ECPG decadd(), decdiv(), decmul(), and decsub() for risnull() input.
Since commit 757fb0e5a9a61ac8d3a67e334faeea6dc0084b3f, these
Informix-compat functions return 0 without changing the output
parameter. Initialize the output parameter before the test call, making
that obvious. Before this, the expected test output has been depending
on freed stack memory. "gcc -ftrivial-auto-var-init=pattern" revealed
that. Back-patch to v13 (all supported versions).
