classes/cmake: Use relative RPATHs
In most cases, the RPATH is stripped out when the ELF file is packages, but by then the damage is done from a reproducible perspective because this absolute path is hashed as part of the build-id generated at link time ([1] has a good explanation). Fortunately, newer cmake has an option to generated relative RPATHs that use $ORIGIN to set the path, so set it in the toolchain file.
