treewide: use ->close to call ProcessIO->CLOSE

This will open the door for us to drop `tie' usage from
ProcessIO completely in favor of OO method dispatch.  While
OO method dispatches (e.g. `$fh->close') are slower than normal
subroutine calls, it hardly matters in this case since process
teardown is a fairly rare operation and we continue to use
`close($fh)' for Maildir writes.
