Originally a web browser was added to build-appliance-image to
enable Hob's use cases that involve opening a URI; with Hob long gone,
a web browser is no longer necessary to have in build-appliance-image.
This will also address the out-of-resources problem when
build-appliance-image builds itself in a VM, as a test case.
