Subject: [PATCH] convert: More robust qemu-ga installation, change paths

Add a commit from the common submodule to attempt to make qemu-ga
installation more robust on Windows.

Rename network configuration Powershell script from "v2vnetcf" to
"network-configuration".  I also dropped the ".ps1" extension as the
modified Firstboot.add_firstboot_powershell function now adds this.

Update the common submodule to get these changes:

Richard W.M. Jones (3):
      mlcustomize: Use Start-Process -Wait to run qemu-ga installer
      mlcustomize: Add Firstboot.firstboot_dir function
      mlcustomize: Place powershell scripts into <firstboot_dir>\Temp

(cherry picked from commit c57ec4fd5d4942d2320aec4a6b01977dabb87f83)
