build: fix build on android (and ppc)

The problem here is that dev_t on most platforms is `long unsigned`, but on android (and ppc?) it's `long long unsigned`. Let's just upcast to `long long unsigned` and use that format string to keep the compilers happy. Safety first! Signed-off-by: Tycho Andersen <tycho.andersen@canonical.com>
