[LTP] [PATCH v3 0/4] landlock network coverage support

[Andrea Cervesato]

This testing suite is meant to test the landlock network support.
The landlock fallback had to be modified in order to support ABI v4
which changed the landlock rules structures. Also, a new test has been
added in landlock08, testing bind() and connect() syscalls support.
A few error checks have been added in the landlock02 test.
