[Impact]
Commit c33a23ff8ffc (selftests: skip seccomp get_metadata test if not real
root) in Bionic tree
Is causing compilation error for the seccomp test in
ubuntu_kernel_selftests:
$ sudo make -C tools/testing/selftests TARGETS=seccomp run_tests
make: Entering directory
'/home/jenkins/ubuntu-gke-4.15-bionic/tools/testing/selftests'

[Fix]
Commit upstream 3aa415dd2128 (selftests: skip seccomp get_metadata test if
not real root) depends on d057dc4e35e1 (seccomp: add a selftest for
get_metadata), but the latter has been reverted on bionic as part of bug
#1837664. The get_metadata testcase doesn't exist anymore, the backport of the
patch ended up changing syscall_restart instead.
So the best solution is to revert c33a23ff8ffc, which is not needed
and is causing trouble.
[Test Case]
Run the seccomp kernel selftests.
[Regression potential]
No regression potential. The commit introduced a regression by being wrongly
backported, so reverting it will fix the issue and has no risk.
