Bug 22323: cronjob runreport.pl CSV add encoding

Cronjob runreport.pl runs SQL reports and can export as CSV.
This export needs to be UTF-8 encoded.

This pathes replaces use of Text::CSV_XS by Text::CSV::Encoded like in other places like tools/viewlog.pl.
It adds a decode of headers bcause they will be encoded lika other lines.

Test plan:
1) Create a new item with itemnotes 'accentué'
2) Create a SQL report with :
SELECT barcode,itemnotes AS itè FROM items WHERE itemnotes LIKE 'accenté'
3) Run this report
4) You see well encoded header and content
5) Run from command line (replace X by report number) :
misc/cronjobs/runreport.pl X --format=csv --csv-header --store-results
6) You well encoded header and content
7) Go to saved reports table
8) Look at saved results of report
9) You well encoded header and content
