elf.5, ld.so.8: Undeprecate DT_RPATH; explain DT_RPATH vs DT_RUNPATH
In elf.5 and ld.so.8, remove deprecation of DT_RPATH
In elf.5, amend the description of DT_RUNPATH and DT_RPATH.
Rationale:
There is no credible path towards removal of DT_RPATH.
Lots of software depend on DT_RPATH as is.
It is used e.g. for testing and in binary installers.
