D11739: tests: add guard check for suid support

REVISION SUMMARY
  This adds a check for setuid and setgid support and guards a part of a test
  requiring this particular filesystem feature.
  
  Such feature is notably missing in the Nix/NixOS build sandbox and was causing
  the whole test to fail for the mercurial package.

REPOSITORY
  rHG Mercurial

BRANCH
  stable
