rust: Use patchelf in place of chrpath to edit rpaths

chrpath has limitations e.g. the original rpath in ELF have to bigger in size
than the one being edited into it by chrpath, some toolchains do not use RPATH
but emit the RUNPATHs into ELF files and chrpath is not able to handle the
runpaths, this is the case with mips and pp32 build of rust, especially
when using clang compiler to build them.

patchelf can do more:

Modify RUNPATH entries
Add RPATH/RUNPATH where none existed
Set longer paths than the original
Convert between RPATH and RUNPATH
