Message:

Test suite: Switch to non-root user namespace before running Apache

Apache tries to switch permissions to a non-root user when started as
root. However, inside a namespace with pseudo root access (needed to
bring up the loopback device of the network namespace) this fails
because no such user exists inside the namespace. Changing to a
non-root user namespace beforehand avoids the issue.

 # MGS_NETNS_ACTIVE is used to track status, there's no harm in calling
