add chomp

[HasegawaTadamitsu]

Thank you very nice gem.

For some reason, the AB shutter I have outputs a newline code. So I'd like you to add a "chomp" at one point. I think this might be useful to someone else, so I'll make a pull request.

part of /sys/**/name output "cpu_thermal\n" "(s) dummy device\n" "ab shutter3\n" <-need chomp "fixedregulator_3v3\u0000"
