Bug 15133: encode correctly email generated by runreport.pl

Bug 15133: encode correctly email generated by runreport.pl

/misc/cronjobs/runreport.pl send badly encoded email in text/csv
(partially ok in HTML).

TEST:

1. Send by email a report containing a subject with accented characters
   and resultset with accented characters. For example:

   ./runreport.pl --subject="éèà" --to=me@home.org  1
   ./runreport.pl --format=html --subject="éèà" --to=me@home.org  1

   The first email contains badly encoded subject & message. The second email
   contains badly encoded subject, but correct message.

2. Apply the patch

3. Repeat 1 => No more strange characters.
