Named return variables should only be used to describe the returned type
further, e.g. `err error` doesn't add any new information and is just
stutter.
Entry collector uses readUintFromFile() function which is defined by
conntrack collector. Thus, it is impossible to build node_exporter w/o
conntrack collector. Fix this by factoring out the function into
helper.go file.
