make_factory_package: sudo if --diskimg is a block device

Browse Source 
Usually make_factory_package operates with normal files that does not need root
permission - except if output is a block device.

This CL tries to grant root permission by sudo if a block device is assigned to
--diskimg.

BUG=chrome-os-partner:2827
TEST=(as normal user) ./make_factory_acpakge --factory FACTORY \
     --release RELEASE --hwid none --diskimg /dev/sde  # completed
