This library is intended for use during release to sign packages which
are then served from pkgs.tailscale.com.
The library is also then used by clients downloading packages for
`tailscale update` where OS package managers / app stores aren't used.

The hardware version in `/proc/sys/kernel/syno_hw_version` does not map
exactly to versions in
https://github.com/SynoCommunity/spksrc/wiki/Synology-and-SynoCommunity-Package-Architectures.
It contains some slightly different version formats.
Instead, `/etc/synoinfo.conf` exists and contains a `unique` line with
the CPU architecture encoded. Parse that out and filter through the list
of architectures that we have SPKs for.
Tested on DS218 and DS413j.

Implement naive update for Synology packages, using latest versions from
pkgs.tailscale.com. This is naive because we completely trust
pkgs.tailscale.com to give us a safe package. We should switch this to
some better signing mechanism later.
I've only tested this on one DS218 box, so all the CPU architecture
munging is purely based on docs.

Extract the self-update logic from cmd/tailscale/cli into a standalone
package that could be used from tailscaled later.
