build: the unix paths retire — configuration, logs, and volumes move into the danos tree

Browse Source 
/etc/init.csv and /etc/devices.csv become /system/configuration/*.csv (the
repo's etc/ moves to system/configuration/, mirroring the runtime tree),
/var/log becomes /system/logs, and /mnt/usb becomes /volumes/usb. The
kernel VFS gains a carve-out so FAT may serve exactly /system/configuration
and /system/logs beneath the initrd-backed /system while /system and /test
themselves stay unshadowable; FAT's single /var mount splits into those two
rewritten mounts. The kvfs readdir check learns /system's third child and
the ramdisk spawn sweep skips the configuration tree.

Suite 106/106.

# /system/configuration/devices.csv — the device→driver registry.
#
# The device manager reads this at boot and binds each device a bus driver
# reports to the driver named here. It is AUTHORITATIVE: a device that no row
# matches goes unbound (logged), never guessed. Edit this file to teach the
# system new hardware — no recompile of the device manager required.
#
# One rule per line, nine comma-separated fields. '#' starts a comment
# (whole-line or trailing); blank lines are ignored. Whitespace around a field
# is trimmed, so columns may be padded for readability.
#
# bus which bus reported the device: pci | usb | acpi
# base PCI base class / USB class (hex)
# class PCI subclass / USB subclass (hex)
# prog_if PCI prog-IF / USB protocol (hex)
# vendor PCI vendor id / USB idVendor (hex)
# device PCI device id / USB idProduct (hex)
# subsystem PCI subsystem, packed (ssvid<<16)|ssid (hex)
# hid ACPI _HID string (e.g. PNP0303); blank for pci/usb
# driver full ramdisk path of the driver to spawn
#
# '*' or an empty field is a wildcard. When several rows match one device the
# MOST SPECIFIC wins (pinning vendor/device/hid beats pinning only a class), so
