[PATCH 4/4] test: set up the outcount file for T380.1

[Michael J Gruber <git@grubix.eu>]

If gdb is present but for some reason `atomicity.py` fails to write to
the output file then the test fails with some ugly bash errors in the
wrong places (because the outcount variable is empty).

Therefore, set up the outcount file with `0` to get the test script to
rund and the test to fail fpr a clearer reason.

Background: We noticed this with arch armhfp emulated on x86_64 in
Fedora's COPR test build environment.
