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@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.
