[PATCH 0/3] Minor improvements to the Spectrum OS boot process

These are all very minor changes. Patch 1 switches from Busybox
switch_root to the util-linux version. Since util-linux moves /dev,
/sys, and /proc to the root filesystem, three calls to mount go away.
Patch 2 adds /dev/fd, /dev/stdin, /dev/stdout, and /dev/stderr symlinks,
to avoid compatibility problems with Spectrum OS's third-party
dependencies. Patch 3 avoids mounting /proc and /sys in the main
system, as the initramfs already did this.
