Wind River Support Network

Description

Premirror is not being used when the rt branch is being parsed when NO_NETWORK is being set and no local cache is found.
This leads to a project build error.

Steps to Reproduce

Use the following steps:

bash-4.3$ git clone --branch WRLINUX_10_19_LTS_RCPL0002 [https://windshare.windriver.com/ondemand/remote.php/gitsmart/WRLinux-lts-19-Core/wrlinux-x]
 -bash-4.3$ ./wrlinux-x/setup.sh --machines qemux86-64
 -bash-4.3$ . ./environment-setup-x86_64-wrlinuxsdk-linux
 -bash-4.3$ . ./oe-init-build-env
 -bash-4.3$ mv ../layers/wrlinux/git ../layers/wrlinux/git2
 -bash-4.3$ vim conf/local.conf
 ...
 #
 # Network Control
 #
 # Disable bitbake from being able to access the network
 BB_NO_NETWORK ?= '0'
 BB_NO_NETWORK_pn-linux-yocto-rt = '1'
 ...
 -bash-4.3$ bitbake wrlinux-image-std
