Bug 21617: statistics.ccode is not long enough (see also DBRev 18.06.00.032)

Warn from a test:
DBD::mysql::st execute failed: Data too long for column 'ccode' at row 1 [for Statement "INSERT INTO statistics
        (datetime,
         branch,          type,        value,
         other,           itemnumber,  itemtype, location,
         borrowernumber,  proccode,    ccode)
         VALUES (now(),?,?,?,?,?,?,?,?,?,?)" with ParamValues: 0="z8LIyIV", 1='issue', 2=undef, 3='', 4='2584', 5='E_QkzaV5Ay', 6='oDnFRZyog2CS2_XoUB_MB2sBxyI3elbFPC_AekxLPrduGTXKnlNoLKEdQrXzpAw5zD1pGbZshV9ydZup', 7='2000005168', 8='', 9='j9ZDn74omZAoZrTOdC4a05SpWRSHPR2apfss7y5V6QJuQnBEk32XWXCfMp7'] at C4/Stats.pm line 138.

The dbrev 18.06.00.032 did not change it from 10 to 80 as in other tables.

We should either truncate to 10 chars in Stats.pm or increase to varchar(80). Since it is varchar and not char, we should not be afraid about size. I choose for the latter here.

Test plan:
Run db rev.
