virtio-inputd: bump 0.1.0 -> 0.2.0; drop orbclient from Cargo.toml

v6.0 prep. Description now says 'writes Linux evdev events to
/scheme/input/evdev' instead of 'orbclient format and pushed to
inputd'. The Cargo.toml orbclient dep is removed; the main.rs
still uses orbclient::Event but will be refactored to use
inputd::EvdevProducerHandle in a follow-up commit (the main.rs
refactor is large enough to warrant its own commit for review).
