Add 82 test suites to check edge cases related to bind() and connect() actions. They are defined with 6 fixtures and their variants: The "protocol" fixture is extended with 12 variants defined as a matrix of: sandboxed/not-sandboxed, IPv4/IPv6/unix network domain, and stream/datagram socket. 4 related tests suites are defined: * bind: Tests bind action. * connect: Tests connect action. * bind_unspec: Tests bind action with the AF_UNSPEC socket family. * connect_unspec: Tests connect action with the AF_UNSPEC socket family. The "ipv4" fixture is extended with 4 variants defined as a matrix of: sandboxed/not-sandboxed, and stream/datagram socket. 1 related test suite is defined: * from_unix_to_inet: Tests to make sure unix sockets' actions are not restricted by Landlock rules applied to TCP ones. The "tcp_layers" fixture is extended with 8 variants defined as a matrix of: IPv4/IPv6 network domain, and different number of landlock rule layers. 2 related tests suites are defined: * ruleset_overlap: Tests nested layers with less constraints. * ruleset_expand: Tests nested layers with more constraints. In the "mini" fixture 4 tests suites are defined: * network_access_rights: Tests handling of known access rights. * unknown_access_rights: Tests handling of unknown access rights. * inval: Tests unhandled allowed access and zero access value. * tcp_port_overflow: Tests with port values greater than 65535. The "ipv4_tcp" fixture supports IPv4 network domain with stream socket. 2 tests suites are defined: * port_endianness: Tests with big/little endian port formats. * with_fs: Tests a ruleset with both filesystem and network restrictions. The "port_specific" fixture is extended with 4 variants defined as a matrix of: sandboxed/not-sandboxed, IPv4/IPv6 network domain, and stream socket. 2 related tests suites are defined: * bind_connect_zero: Tests with port 0. * bind_connect_1023: Tests with port 1023. Test coverage for security/landlock is 92.4% of 710 lines according to gcc/gcov-13.
