Phil Estes c1642c937d Fix relative path execution of docker daemon in reexec.Self() 
After the new libcontainer API, the reexec.Self() output of the daemon
binary is used as the libcontainer factory InitPath.  If it is relative,
it can't be found at container start time.  This patch solves the
problem by making sure that we return a rooted/absolute path if a
relative path is used.

reexec

The reexec package facilitates the busybox style reexec of the docker binary that we require because of the forking limitations of using Go. Handlers can be registered with a name and the argv 0 of the exec of the binary will be used to find and execute custom init paths.
