b45242c50f Add chroot support to core
Since the recent move of the process creation into core, the original chroot trampoline
mechanism implemented in 'os/src/app/chroot' does not work anymore. A
process could simply escape the chroot environment by spawning a new
process via core's PD service. Therefore, this patch moves the chroot
support into core. So the chroot policy becomes mandatory part of the
process creation.  For each process created by core, core checks for
'root' argument of the PD session. If a path is present, core takes the
precautions needed to execute the new process in the specified chroot
environment.

This conceptual change implies minor changes with respect to the Genode
API and the configuration of the init process. The API changes are the
enhancement of the 'Genode::Child' and 'Genode::Process' constructors to
take the root path as argument. Init supports the specification of a
chroot per process by specifying the new 'root' attribute to the
'<start>' node of the process. In line with these changes, the
'Loader::Session::start' function has been enhanced with the additional
(optional) root argument.

df6a2f1365 chroot_loader: Fix run script for 64bit environment
The /lib64 path is required here to allow execution of 64bit binaries.

Here is an example-ldd call:

$ ldd /bin/ls
	linux-vdso.so.1 =>  (0x00007fffdedff000)
	libselinux.so.1 => /lib/x86_64-linux-gnu/libselinux.so.1 (0x00007f4ae207d000)
	librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007f4ae1e75000)
	libacl.so.1 => /lib/x86_64-linux-gnu/libacl.so.1 (0x00007f4ae1c6c000)
	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f4ae18af000)
	libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f4ae16ab000)
	/lib64/ld-linux-x86-64.so.2 (0x00007f4ae22bd000)
	libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f4ae148d000)
	libattr.so.1 => /lib/x86_64-linux-gnu/libattr.so.1 (0x00007f4ae1288000)

Fixes #249
