qa: Ignore `lsof` warnings on NetBSD
On NetBSD, `lsof` can produce the following warnings:
1. "created device cache file: ..." - usually happens in a CI
environment.
2. "compiled for NetBSD release 10.0; this is 10.1." or similar - when
the `lsof` binary package is installed on a point release.
This change suppresses both warnings printed to stderr and fixes the
affected tests.
What changed, and why it matters
This is a minor test-framework fix for Bitcoin Core's automated QA on NetBSD. It tells the `lsof` network tool to ignore harmless warning messages about device cache files and operating-system version mismatches so those warnings don't break tests. There is no security vulnerability or user-facing change.
No security action needed. Treat as a normal QA/test portability fix.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The commit modifies test/functional/test_framework/netutil.py to pass lsof flags -Di and -w when running on NetBSD. -Di disables the device cache file (already used on FreeBSD), and -w suppresses warnings such as point-release mismatch messages. This only affects the test harness’s parsing of lsof stderr output and has no runtime impact on Bitcoin Core nodes.
