PT-143 Fixed key handling

Browse Source 
When tehre is a table having a key like:
PRIMARY KEY (`id`,`start`,`end`,`user_id`(13),`interval`),
DBI driver is taking (13) as part of the field name.
Fixed the way pt-archiver composes the key using DBI cols field
instead of the colnames field since the cols field has the correct
field names for the key.
