pack: Relocatable wrapper leaves root available to child processes.
Fixes <https://bugs.gnu.org/44261>.
Reported by Jan Nieuwenhuizen <janneke@gnu.org>.
* gnu/packages/aux-files/run-in-namespace.c (exec_in_user_namespace):
Add call to 'prctl'. Call 'mount' for NEW_ROOT and define 'is_tmpfs'.
When IS_TMPFS is true, call 'umount' and 'rmdir' after 'waitpid';
otherwise, call 'rm_rf' only when 'waitpid' returns -1 the second time.
(exec_with_loader): Call 'prctl'. Remove NEW_ROOT only when 'waitpid'
returns -1 the second time, otherwise leave it behind.
* tests/guix-pack-relocatable.sh (wait_for_file): New function.
Add test.
