qrexec: fix deadlock in qrexec-client

When VM-VM qrexec service is called, two qrexec-clients are connected in
dom0. If both VMs are sending data simultaneously it can happen that
both qrexec-client processes will call write(2) and none of them will be
reading -> deadlock.
Solve it by handling I/O in two separate threads (one for reading from
VM, another for writing), at any time qrexec-client is ready to accept
data from either direction.
