Rename chromeos-microbenchmark package to libchromeos-microbenchmark-dev

This package only contains a header file and a static library, so
libfoo-dev naming is more conventional, and it lets chromiumos-build
know that it can cross-convert the resulting package and install it to
satisfy future build-dependencies without having to add a special case.
