[PATCH net-next v2 0/4] net: selftests: adjustments to ipv6_flowlabel_mgr

The ipv6_flowlabel_mgr test file was lacking coverage for the IPV6_FL_A_RENEW
action, and the IPV6_FL_F_REMOTE and IPV6_FL_F_REFLECT flags. The first
three patches from this set aim to add a proper test case for each.

The fourth patch proposes the adoption of "kselftest_harness.h" helpers,
improving code readability and conforming to the implementation of the most
recent selftests.

---
v2:
- Apply missing scripts/checkpath.pl fixes and other formatting
  enhancements
- Add new basic IPV6_FL_A_RENEW tests
- Put label after IPV6_FL_F_REMOTE test, freeing the value for a
  subsequent test
- Delegate flowlabel_consistency configuration to wrapper sh script
  instead of doing it on the main test code
- Skip IPV6_FL_F_REFLECT tests if flowlabel_consistency is set,
  instead of failing the test or attempting to change it
- Compare resulting error for failure assertions
