samples/landlock: Format with clang-format 
Let's follow a consistent and documented coding style.  Everything may
not be to our liking but it is better than tacit knowledge.  Moreover,
this will help maintain style consistency between different developers.

This contains only whitespace changes.

Automatically formatted with:
clang-format-14 -i samples/landlock/*.[ch]

samples/landlock: Add clang-format exceptions 
In preparation to a following commit, add clang-format on and
clang-format off stanzas around constant definitions.  This enables to
keep aligned values, which is much more readable than packed
definitions.
