Rename Input.h to vncInput.h to fix building on case-insensitive FS
I am cross-compiling from macOS for a FreeBSD-derived system so my host file system is case insensitive but the target isn't. Without this change I get the following warnings which show that the vnc "Input.h" is being included from mi/mi.h instead of the xserver "input.h": ``` In file included from /Users/alex/cheri/xvnc-server/hw/vnc/Input.c:33: /Users/alex/cheri/xvnc-server/mi/mi.h:55:10: warning: non-portable path to file '"Input.h"'; specified path differs in case from file name on disk [-Wnonportable-include-path] #include "input.h" ^~~~~~~~~ "Input.h" ```
