Mount the new system as 'postinstall_file' in postinstall.
When mounting the new filesystem on /postinstall, we need to override
the file attributes from the new system (unknown to the current selinux
policies) with a consistent label that will be used only in the context
of postinstall. This patch passes an extra option to mount(2) in
Brillo and Android to achieve this.
Bug: 27177071
TEST=Deployed a postinstall script with `ls -laZ`, contents show "postinstall_file".
