asciidoctor: fix encoding error for non-ASCII translations

File.read without an explicit encoding uses Ruby's default external
encoding, which depends on the system locale. On systems where it
resolves to US-ASCII (e.g. some Debian configurations), reading
translated man page files with non-ASCII content (such as Arabic)
fails with "source is either binary or contains invalid Unicode data".

Specify encoding: 'UTF-8' explicitly so the string is correctly
tagged regardless of locale.
