Create new virtmgr binary from virtualizationservice
To bootstrap separation of virtualizationservice into two binaries
(global service and user instance), start by compiling a second binary
out of the same source code, just using a diffrent main source file.
The new binary has a command line interface that takes two file
descriptors - a socketpair() fd to start RpcBinder server on, and
a pipe() fd to use for signalling when the server has been started.
The process registers a death notification to kill itself when the
parent process has died.
