    install*.sh: add short sleep after parted commands
    
    I wasn't able to install to my Optane SSD due to the following error:
    
    Formatting /dev/nvme0n1p1 to vfat...
    mkfs.fat 4.1 (2017-01-24)
    mkfs.vfat: unable to open /dev/nvme0n1p1: No such file or directory
    Target install-efi failed
    
    A couple lines later I see:
    
    [    10.265401]  nvme0n1: p1 p2 p3
    
    Then looking at the device itself after booting from a USB stick:
    
    root at intel-corei7-64: ~# ls /dev/nvme0n1*
    /dev/nvme0n1 /dev/nvme0n1p1 /dev/nvme0n1p2 /dev/nvme0n1p3
    
    So it looks like the parted commands return before the device node is
    actually created.
    
    Work around this issue by waiting for device nodes for a short duration.
