pmp-check-mysql-processlist: "copy to table" counter always 0

[Roman Vynar]

Regex for counting "copy to table" processes in pmp-check-mysql-processlist is wrong which makes a counter to be 0 all the time.

Possible states:
        State: copy to tmp table
        State: Copying to tmp table on disk
        State: Copying to tmp table
        State: Copying to group table

Fix:
- COPYIN=$(count_mysql_processlist "${TEMP}" "State" "opy.*table*")
+ COPYIN=$(count_mysql_processlist "${TEMP}" "State" ".*opy.* to.* table.*")
