Subject: [PATCH] test/file-verify.t: Don't run over mlock limit when run as
 non-root

test/file-verify tries to get 2MB of pinned memory at once, which is
higher than the default allowed for non-root users in older
kernels (64kb before v5.16, nowadays 8mb).  Skip the test for non-root
users if the registration fails instead of failing the test.
