Extra file-E files are created during replace, when using FreeBSD

[digimokan]

#259 was resolved for MacOS, but FreeBSD (and maybe other BSD or non-Linux OSs) do not use GNU sed as well.

I can verify that adding a check for uname == 'FreeBSD' in sed.lua resolves the issue for FreeBSD. Let me know if you would like me to submit a pull request.

I tried #267 and it works fine on FreeBSD. Thank you.
