json-schema-validator: Remove absolute path in INSTALL_CMAKE_DIR

Can't found properly in the sysroot dir due to the absolute path in
INSTALL_CMAKE_DIR.

Fixes:
The imported target "nlohmann_json_schema_validator" references the file
"/usr/lib/libnlohmann_json_schema_validator.so.2.1.0"
but this file does not exist.
