syscall.Unshare is the sort of system call that may be blocked in a container environment, and experience has shown that different container implementations choose from a variety of different error codes for blocked syscalls. In particular, the patch in https://git.alpinelinux.org/aports/tree/community/go/tests-unshare-enosys.patch seems to suggest that the container environment used to test the Go distribution on Alpine Linux returns ENOSYS instead of EPERM. The existing testenv.SyscallIsNotSupported helper checks for the kinds of error codes we have seen from containers in practice, so let's use that here. For #62053. Updates #29366.
