Hi,

A couple of tests fail in a restricted environment, like when running
under a systemd service or container with a seccomp filter set. Detect
such environments and mark the test as UNSUPPORTED instead of failing.

The following 4 patches are needed to get glibc-fedora-x86_64 builder,
which runs as a container, to zero FAIL:
https://builder.sourceware.org/buildbot/#/builders/glibc-fedora-x86_64

- time/tst-clock2.c: clock_settime CLOCK_MONOTONIC might return EPERM
- tst-pkey.c: Handle no permission to alloc memory protection keys
- tst-pidfd.c: Test is UNSUPPORTED without
  PTRACE_MODE_ATTACH_REALCREDS
- tst-personality.c: Handle personality failing with errno EPERM

Patches also available at:
https://code.wildebeest.org/git/user/mjw/glibc/log/?h=container-perms

Cheers,

Mark
