Since the tailscaled binaries that we distribute are static and don't
link cgo, we previously wouldn't fetch group IDs that are returned via
NSS. Try shelling out to the 'id' command, similar to how we call
'getent', to detect such cases.

58ab66ec51 added LDAP support
for #4945 by shelling out to getdent.
It was supposed to fall back to the old method when getdent wasn't
found, but some variable name confusion (uid vs username) meant the
old path wasn't calling the right lookup function (user.LookupId
instead of user.Lookup).
Which meant that changed probably also broke FreeBSD and macOS SSH
support in addition to the reported OpenWRT regression.
The gokrazy support didn't look right either.

The previous commit 58ab66e added ssh/tailssh/user.go as part of
working on #4945. So move some more user-related code over to it.
