Assume kernel has devtmpfs enabled --> cleanup device creation & mount

Cleanup device creation and initial mount by assuming that the kernel
has devtmpfs enabled.  This is the default for most modern GNU/Linux
distributions.  See http://lwn.net/Articles/331818/ for more info.

Also, since finit is targeted at deeply embedded systems hooks for the
BusyBox udev replacement, mdev has been added.  If MDEV is defined in
the build it will take care of both hotplugging of devices and initial
setup of /dev
