[rust] Switch LTO flavor to "thin"
Bug: http://b/202032071
Thin LTO provides similar performance gains to full LTO but takes less
time during build.
Thin LTO also doesn't cause the error with `-C lto` and `-C
llvm-args=--runtime-counter-relocation` in b/202032071.
Test: presubmit
Test: verify b/202032071
