net: add skb_segment kunit test
Add unit testing for skb segment. This function is exercised by many
different code paths, such as GSO_PARTIAL or GSO_BY_FRAGS, linear
(with or without head_frag), frags or frag_list skbs, etc.
It is infeasible to manually run tests that cover all code paths when
making changes. The long and complex function also makes it hard to
establish through analysis alone that a patch has no unintended
side-effects.
Add code coverage through kunit regression testing. Introduce kunit
infrastructure for tests under net/core, and add this first test.
This first skb_segment test exercises a simple case: a linear skb.
Follow-on patches will parametrize the test and add more variants.
Tested: Built and ran the test with
make ARCH=um mrproper
