Just a happy path test.
Christian Brauner <brauner@kernel.org> says:
Update OPENAT2_REGULAR fallback define to match upper-32-bit UAPI value.
Port the test to the kselftest_harness TEST*/FIXTURE framework to match
the migrated openat2_test.c, and add a regression test ensuring
open()/openat() keep ignoring the internal __O_REGULAR carrier bit.

Add tests for the new O_EMPTYPATH flag of openat(2)/openat2(2).
Also, the current openat2 tests include a helper header file that
defines the necessary structs and constants to use openat2(2), such as
struct open_how. This may result in conflicting definitions when the
system header openat2.h is present as well.
So add openat2.h generated by 'make headers' to the uapi header
files in ./tools/include and remove the helper file definitions of
the current openat2 selftests.

These tests were written in the early days of selftests' TAP support,
the more modern kselftest harness is much easier to follow and maintain.
The actual contents of the tests are unchanged by this change. Most of
the diff involves switching from the E_* syscall wrappers we previously
used to ASSERT_EQ(fn(...), 0) in tests and helper functions.
The first pass of the migration was done using Claude, followed by a
manual rework and review.

This is a bit ugly, but in the next patch we will move to using
kselftest_harness.h -- which doesn't play well with being included in
multiple compilation units due to duplicate function definitions.
Not including kselftest_harness.h would let us avoid this patch, but the
helpers will need include kselftest_harness.h in order to switch to
TH_LOG.

These tests really should've always belonged there, doubly so now that
they include a lot of other generic filesystem-related tests.
