This change reintroduces UserProfile.Groups, a slice that contains
the ACL-defined and synced groups that a user is a member of.
The slice will only be non-nil for clients with the node attribute
see-groups, and will only contain groups that the client is allowed
to see as per the app payload of the see-groups node attribute.
For example:
```
"nodeAttrs": [
{
"target": ["tag:dev"],
"app": {
"tailscale.com/see-groups": [{"groups": ["group:dev"]}]
}
},
[...]
]
```
UserProfile.Groups will also be gated by a feature flag for the time
being.

Users on FreeBSD run into a similar problem as has been reported for
Linux #11682 and fixed in #11682: because the tailscaled binaries
that we distribute are static and don't link cgo tailscaled fails to
fetch group IDs that are returned via NSS when spawning an ssh child
process.
This change extends the fallback on the 'id' command that was put in
place as part of #11682 to FreeBSD. More precisely, we try to fetch
the group IDs with the 'id' command first, and only if that fails do
we fall back on the logic in the os/user package.

Specify the app apability that failed the test, instead of the
entire comma-separated list.

Also consolidates variable and header naming and amends the
CLI behavior
* multiple app-caps have to be specified as comma-separated
list
* simple regex-based validation of app capability names is
carried out during flag parsing

Given that we filter based on the usercaps argument now, truncation
should not be necessary anymore.
