xh_cidx: include khashl.h to placate cppcheck(1)

cppcheck(1) will complain about things normal compilers don't.
While this #include is unnecessary to us since we only have a
single compilation unit and don't intend to reuse this header
elsewhere, it seems mostly harmless since GNU and clang
preprocessors should be able to optimize out redundant headers,
anyways, even w/o `#pragma once'.
