taxonomy: remove Capabilities and Interworking.
Experience in the real world shows that the Capabilities bitmask
isn't as useful as it seemed. Many of the bits are dynamic, so
client bitmasks change frequently and leads to a combinatorial
explosion in signatures. Also, differences we thought we saw between
clients were mostly differences in the environment, not useful as
signatures.
Similarly, what we thought were real differences in Interworking
between devices turned out to be bugs in iOS versions setting the
bitmask incorrectly. The presence or absence of the Interworking
field is a useful signal (and is already in the base signature),
the contents of the Interworking bitmask really aren't useful.
