[clang] [flang] [flang][Driver] When linking with the Fortran runtime, the `addArchSpecificRPath()` should be called too (PR #114837)

`addSanitizerRuntime` and `addOpenMPRuntime` are already calling `addArchSpecificRPath`. It it a problem if rpath is added multiple times?

Compiler-rt libs (`libclang_rt.*.a`) are added as absolute paths, shouldn't the Fortran-runtime do the same?
