Currently, logrus is used from the Go part of runc init, mostly for a few debug messages (see setns_init_linux.go and standard_init_linux.go), and a single warning (see rootfs_linux.go). This means logrus is part of init implementation, and thus, its setup belongs to StartInitialization(). Move the code there. As a nice side effect, now we don't have to convert _LIBCONTAINER_LOGPIPE twice. Note that since this initialization is now also called from libct/int tests, which do not set _LIBCONTAINER_LOGLEVEL, let's make _LIBCONTAINER_LOGLEVEL optional.
