busybox: provide /etc/mdev.conf if mdev is used
Without an mdev.conf file installed, mdev generates some /dev entries in
an incorrect or non-standard way. Some examples:
1. /dev/null has permissions 660, but it should be accessible to normal
users;
2. alsa devices get created in /dev, not /dev/snd as is more common,
and as the default value of BR2_PACKAGE_ALSA_LIB_DEVDIR suggests;
3. event<N> files are created in /dev, not /dev/input.
This mdev.conf is a selection from the examples provided in the busybox
sources with minor tweaks.
