initrdscripts: exec switch_root(8) instead of chroot(1)
This should address for NOR-flash systems the same problem that was
fixed for MMC-based systems in commit b5cbe9bbba67 ("phosphor-mmc-init:
exec switch_root(8) rather than chroot(1)").
By virtue of switch_root(8) wiping out everything in the old root it
also avoids wasting a few megabytes of memory keeping that filesystem
around without any way of reaching it.
