nptl: rseq failure after registration on main thread is fatal
This simplifies the application programming model.

Browser sandboxes have already been fixed:

  Sandbox is incompatible with rseq registration
  <https://bugzilla.mozilla.org/show_bug.cgi?id=1651701>

  Allow rseq in the Linux sandboxes. r=gcp
  <https://hg.mozilla.org/mozilla-central/rev/042425712eb1>

  Sandbox needs to support rseq system call
  <https://bugs.chromium.org/p/chromium/issues/detail?id=1104160>

  Linux sandbox: Allow rseq(2)
  <https://chromium.googlesource.com/chromium/src.git/+/230675d9ac8f1>
