hostinfo: detect AWS Lambda as a container.
...
AWS Lambda uses Docker containers but does not
have the string "docker" in its /proc/1/cgroup.
Infer AWS Lambda via the environment variables
it sets.

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:/
6:perf_event:/
5:net_cls,net_prio:/
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.

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.
