Sebastiaan van Stijn 94462d8f5d oci/deviceFromPath(): correctly check device types ...

This ports the changes of 95a59bf206
to this repository.

From that PR:

    (mode&S_IFCHR == S_IFCHR) is the wrong way of checking the type of an
    inode because the S_IF* bits are actually not a bitmask and instead must
    be checked using S_IF*. This bug was neatly hidden behind a (major == 0)
    sanity-check but that was removed by [1].

    In addition, add a test that makes sure that HostDevices() doesn't give
    rubbish results -- because we broke this and fixed this before[2].

    [1]: 24388be71e ("configs: use different types for .Devices and .Resources.Devices")
    [2]: 3ed492ad33 ("Handle non-devices correctly in DeviceFromPath")
