Bug 19756: Fix encoding issues during the update DB process

To display the output of the updatedatabase.pl under Plack, we redirect
the output to a temporary file, read it, then display it.
We need to open it specifying the correct encoding (utf-8).

Test plan:
1. MariaDB [koha_kohadev]> update systempreferences set value="17.1100000"
where variable="version";
2. restart plack
3. Login
4. Make the update from the interface
=> Without this patch you will see encoding issue:
Upgrade to 17.12.00.000 done (TÄ\93 tÅ\8dia, tÄ\93 haumatia)
=> With this patch applied you will see :
Upgrade to 17.12.00.000 done (Tē tōia, tē haumatia)
