ino: Use picocom rather than minicom
virtualbox: Disable depmod only where necessary.

Traversing the full source tree is unneccessary, because the calls are
only done within make files. Hence we only substitute make files now.

virtualbox: Enable hardening by default.

VirtualBox with hardening support requires the main binaries to be
setuid root. Using VBOX_WITH_RUNPATH, we ensure that the RPATHs are
pointing to the libexec directory and we also need to unset
VBOX_WITH_ORIGIN to make sure that the build system is actually setting
those RPATHs.

The hardened.patch implements two things:

 * Set the binary directory to the setuid-wrappers dir so that
   VboxSVC calls them instead of the binaries from the store path. The
   reason behind this is because nothing in the Nix store can have the
   setuid flag.
 * Excempt /nix/store from the group permission check, because while it
   is group-writeable indeed it also has the sticky bit set (and also
   the whole store is mounted read-only on most NixOS systems), so we're
   checking on that as well.

Right now, the hardened.patch uses /nix/store and /var/setuid-wrappers
directly, so someone would ever want to change those on a NixOS system,
please provide a patch to set those paths on build time. However, for
simplicity, it's best to do it when we _really_ need it.

Add primus and extend bumblebee to support 32bit/64bit multilib architectures.
Using primusrun will work as expected in a multilib environment. Even if the initial program
executes a antoehr program of the another architecture. Assuming the program does not modify
LD_LIBRARY_PATH inappropriately.

This does not update virtualgl for seemless multilib. I was unable to get a mixed 64/32 bit
environment to work with VirtualGL. The mechanism VirtualGL uses to inject the fake GL library would
fail if both 32bit and 64 bit libraries were in the environment. Instead the bumblebee package
creates a optirun32 executable that can be used to run a 32bit executable with optimus on a 64 bit
host. This is not created if the host is 32bit.

For my usage, gaming under wine, the primusrun executable works as expected regardless of
32bit/64bit.
