selftests: net: create own netns in ipv6_flowlabel_mgr

Browse source

Have ipv6_flowlabel_mgr create and configure its own network
namespace (unshare(CLONE_NEWNET) + bring up lo), the same way
ipv6_fragmentation.c and icmp_rfc4884.c already do, instead of
relying on the in_netns.sh wrapper script.

The setup can then be reused across tests through fixtures and
provide isolated network environments for each test in the case
of a future adoption of kselftest_harness.

It also avoids the leak of modifications to the netns in case the
user runs the test file directly, outside the wrapper and without
the in_netns.sh file.
