kselftest/openat2: test for OPENAT2_REGULAR flag

Browse source

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.
