[PATCH] send-email: Add CCs from additional commit tags

[Soren Brinkmann <soren.brinkmann@xilinx.com>]

Add email addresses from additional commonly used tags to the CC-list of
patches. Additional tags are:
 - Acked-by
 - Reviewed-by
 - Tested-by
 - Reported-by
 - Reviewed-and-tested-by

--suppress-cc=ack suppresses these additional CCs.
