spdx: add BSD-3-Clause identifiers to userspace/tools/scripts sources

Sweep of the 155 tracked C/Python/shell files under userspace/ (excluding
the MIT-licensed vendored userspace/extern/), tools/ and scripts/ that had
no per-file license identifier. Each gains the minimal two-line header in
the area's existing form: 'SPDX-License-Identifier: BSD-3-Clause' plus
'Copyright (c) 2026 Open-IOV contributors'; shebang and coding lines stay
first. No other content touched. kernel/** is deliberately out of scope
(recorded as a follow-up in CODESTD-REPORT-2026-10-08.md): its SPDX
coverage and MODULE_LICENSE normalization need their own GPL-2.0 pass.
