Use the same rpaths for tests and binaries and cc and rust
Rust and cc binaries currently use $ORIGIN/lib64:$ORIGIN/../lib64 as the
rpath, and cc tests add $ORIGIN/../../lib64:$ORIGIN/../../../$ORIGIN:$ORIGIN.
This causes problems when a binary is included as test data in
out/host/linux-x86/testcases/<test dir>/<CPU>/<test>, as the
binaries can't find the libraries in out/host/linux-x86/lib64.
Use the same rpath for test and binaries, and for cc and rust.
