Make display unique id stable across x86 and x86_64 builds
... by using a minimal version of CityHash64 for the hash function.
std::hash differs between x86 and x86_64 and also:
"Hash functions are only required to produce the same result for the
same input within a single execution of a program;"
This is problematic for input device configuration files which
reference the display unique id.
