crosvm: Support cros-rust version crosvm ebuild

To support eclass migration for crosvm ebuild from crate to cros-rust. This CL need to be built with cros-rust version crosvm ebuild. - Upgrage crate cc from 1.0.15 to 1.0.25. - Change local tempdir version from 0.3.5 to 0.3.7 for ebuild integration. - Remove 9s directory since it's moved to platform2.
