[Spice-devel] [PATCH spice] inputs_channel: Fix wrong handling of key up/down on big endian

The client will send 0x000000## codes for regular keys, and 0x0000##e0 codes
for extended keys. The current code which simply walks the uint32_t code in
memory order relies on the memory order being little endian, which will
clearly fail on big endian machines, this fixes this.
