selftests: rds: Add SUDO_USER env variable

Browse source

This patch modifies rds selftests to use the environment variable
SUDO_USER for tcpdumps if it is set.  This is needed to avoid chown
operations on the vng 9pfs which is not supported.  Passing a user
listed in sudoers avoids the tcpdump privilege drop which may
otherwise create empty pcaps
