Denton Gentry 224e60cef2 hostifo: update LXC, add Cloud Run.
Recent LXC support no longer has "lxc" in /proc/1/cgroup:
    # cat /proc/1/cgroup
    12:freezer:/
    11:rdma:/
    10:cpuset:/
    9:pids:/
    8:blkio:/
    7:devices:/

    4:memory:/
    3:hugetlb:/
    2:cpu,cpuacct:/
    1:name=systemd:/init.scope
    0::/init.scope

Look for fuse.lxcfs in /proc.mounts in addition:
    # grep lxc /proc/mounts
    lxcfs /proc/cpuinfo fuse.lxcfs ...
    lxcfs /proc/diskstats fuse.lxcfs ...
    lxcfs /proc/loadavg fuse.lxcfs ...
    lxcfs /proc/meminfo fuse.lxcfs ...
    lxcfs /proc/stat fuse.lxcfs ...
    lxcfs /proc/swaps fuse.lxcfs ...
    lxcfs /proc/uptime fuse.lxcfs ...
    lxcfs /sys/devices/system/cpu/online fuse.lxcfs ...

Add Knative detection by looking for the environment variables
which are part of its container contract.

Brad Fitzpatrick ef15096a7d control/controlclient, version/distro: detect NixOS explicitly
The fallthrough happened to work in controlclient already due to the
/etc/os-release PRETTY_NAME default, but make it explicit so it
doesn't look like an accident.

Also add it to version/distro, even though nothing needs it yet.
