Subject: [PATCH] Use system-compatible include path for `xxhash.h`

Distributors that build mold against the system-provided xxHash package
expect its header file `xxhash.h` in the top-level include directory,
not in an `xxhash` subdirectory. Adjust the include path and the
`#include` directive accordingly.
