hostnamed: make chassis type configurable via /etc/machine-info
For many usecases it is useful to store the chassis type somewhere, and /etc/machine-info sounds like a good place. Ideally we could always detect the chassis type from firmware, but frequently that's not available and in many embedded devices probably entirely unrealistic. This patch adds a configurable setting CHASSIS= to /etc/machine-info and exposes this via hostnamectl/hostnamed. hostnamed will guess the chassis type from DMI if nothing is set explicitly. I also added support for detecting it from ACPI, which should be more useful as ACPI 5.0 actually knows a "tablet" chassis type, which neither DMI nor previous ACPI versions knew. This also enables DMI-based and ACPI-based detection for non-x86 systems as ACPI is apparently coming to ARM platforms soon. I tried to minimize the vocabulary of chassis types understood and added: desktop, laptop, server, tablet, handset. This is much less than either APCI or DMI know. If we need more types later on we can easily add them.
