Fix compilation without conntrack collector
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. Signed-off-by: Pavel Borzenkov <pavel.borzenkov@gmail.com>
