Merge branch 'retire-progs-test_sock_addr'

Jordan Rife says:

====================
Retire progs/test_sock_addr.c

This patch series migrates remaining tests from bpf/test_sock_addr.c to
prog_tests/sock_addr.c and progs/verifier_sock_addr.c in order to fully
retire the old-style test program and expands test coverage to test
previously untested scenarios related to sockaddr hooks.

This is a continuation of the work started recently during the expansion
of prog_tests/sock_addr.c.

=======
Patches
=======
* Patch 1 moves tests that check valid return values for recvmsg hooks
  into progs/verifier_sock_addr.c, a new addition to the verifier test
  suite.
* Patches 2-5 lay the groundwork for test migration, enabling
  prog_tests/sock_addr.c to handle more test dimensions.
* Patches 6-11 move existing tests to prog_tests/sock_addr.c.
* Patch 12 removes some redundant test cases.
* Patches 14-17 expand on existing test coverage.
