vbox: Implement virDomainSendKey

Since the holdtime is not supported by VBOX SDK, it's being simulated
by sleeping before sending the key-up codes. The key-up codes are
auto-generated based on XT codeset rules (adding of 0x80 to key-down)
which results in the same behavior as for QEMU implementation.
