syscall: TestGroupCleanupUserNamespace test failure on Fedora [1.16 backport] #46769
Description
@ianlancetaylor requested issue #46752 to be considered for backport to the next 1.16 minor release.
@gopherbot Please open backport issues
This test failure happens when running minor releases on some systems. The fix is tiny, so may as well backport to avoid unexpected test failures when people build those releases from source.
