Subject: [PATCH RFC 1/3] selftests/landlock: move sandbox_type to common

The enum sandbox_type describes three execution modes for Landlock
test tasks:
  - NO_SANDBOX: no Landlock domain
  - SCOPE_SANDBOX: scoped Landlock domain
  - OTHER_SANDBOX: placeholder for future cases

This enum was defined in scoped_multiple_domain_variants.h but is
needed by upcoming cross-domain test variants. Rather than duplicate
the definition, move it to scoped_common.h which is already included
by all scope-related tests.

This is a pure refactor with no functional changes to test binaries.
