build_rootfs.sh: Add 8250.nr_uarts=X
When bootstrapping with recent GKI images, the 8250 serial devices will
not be available to userspace due to a mitigation made for devices
without 8250 serial. On devices where these are known to exist,
8250.nr_uarts must be set. Add it to build_rootfs.sh as well. This has
no harmful effect on older kernels.
