fix(iso): honor TMPDIR for the QEMU boot-test disk/serial log

Browse Source 
Both the 20G sparse qcow2 test disk and the serial console log were
hardcoded to /tmp regardless of $TMPDIR, so pointing the ISO release
build at a disk-backed scratch dir (to avoid tmpfs space pressure)
would not have covered this stage. Falls back to /tmp when TMPDIR is
unset — no behavior change for existing callers.
