Make letsencrypt-auto indentation consistent (#3986)

* Make certbot-auto indentation consistent

Since a majority of certbot-auto uses 2 spaces per indentation level,
made indentation in letsencrypt-auto and platform-specific shell scripts
a consistent 2 spaces

Fixes #3902

* Fix last `if` statement body in rpm_common.sh
