Subject: [PATCH] server: clean supplementary groups when setuid
Upstream: merged
References: https://github.com/NetworkBlockDevice/nbd/commit/0cd9e3ba2a0f54d930d813bfde9ff9d57a12d9ed

When nbd-server drops privileges, it was leaving supplementary
groups untouched. As nbd-server was normally dropping from root,
nbd-server kept membership to root supplementary groups.
