[PATCH net-next] selftests: net: separate ipv6_flowlabel_mgr test

[Marcelo Mendes Spessoto Junior]

The ipv6_flowlabel_mgr used to be a component of a broader overall
flow label test, defined in the ipv6_flowlabel.sh file. This wrapper
script called tests defined on ipv6_flowlabel.c and
ipv6_flowlabel_mgr.c files, using predefined parameters and enforcing
the in_netns.sh helper to set network namespaces for each test env.

However, the ipv6_flowlabel_mgr.c was drastically changed recently.
These modifications led to the mgr tests becoming a self contained and
independent test suite, enforcing netns creation by itself and
not relying on the ipv6_flowlabel.sh wrapper for proper test execution
anymore. Therefore, remove the mgr tests from the wrapper and update
the Makefile to handle it as a standalone test program instead.
