failure with run/noux_net_openssh_interactive

[Tim Newsham]

I am using 14.11 with its version of nova
REV(nova) := 2b4f2803218cf92e2982b47a370d60b18bb78a15

applying your patch fixes the boot time problems.
Now it boots to bash.  When I tried to run an ssh command
"ssh -p 1234 1.2.3.4 uptime" though, I got a fault:

[init -> noux] replay: missing ds_info for dataspace at addr 0x2000
unmapping of managed dataspaces not yet supported
unmapping of managed dataspaces not yet supported
no RM attachment (READ pf_addr=0 pf_ip=10f36b1 from a44fefc6 /bin/ssh)
virtual void Genode::Signal_session_component::submit(Genode::Signal_context_capability,
unsigned int): invalid signal-context capability
static void Genode::Pager_object::_page_fault_handler(): unhandled
page fault, 'pager:/bin/ssh' address=0x0 ip=0x10f36b1

The noux-pkg/openssh/install/bin/ssh binary doesnt have any segments
in the 0x10f36b1 range.
