Run partition editor with script flag to avoid prompting user

Bug 5443
When running on HyperV, install-system appeared to hang because
although hda existed, it had no information so parted was prompting
for retry.  Use the -s flag (never prompt) at all the places
in install-system/install-image where we don't want to have
user interaction.
