If the output from opkg-query-helper.py is empty, output.split('\n')
would result in a list containing one element which is an empty string
while iterating over each line in the output. An exception is then
thrown by the line:
pkg, pkg_file, pkg_arch = line.split()
with the message:
Exception: ValueError: need more than 0 values to unpack
To avoid this, we add a condition to only split the output if it isn't
empty.
