release.yml: check /src/ for .deb (not /src/_src/) for both builds

The Makefile mv's the produced .deb into /src/ (POSTIT_OUT_DIR
default = parent of build dir). The post-build 'ls' check was
running in cwd /src/_src/, missing the .deb every time, which
made the build step fail even when dpkg-deb had succeeded.

Worse: amd64 step exited 1 first, so arm64 step never ran. The
'no arm64 .deb' symptom was a red herring — it was caused by
this earlier amd64 false negative, not by an arm64 build failure.

Fix: ls /src/postit_*...deb explicitly. If both builds succeed,
we'll see both .deb in the next step. If only amd64 shows up,
we'll know arm64 actually failed (and where, via set -x).
