[PATCH] checkpatch.pl: add union and struct to the exceptions list

[Stefani Seibold <stefani@seibold.net>]

This patch add the struct and union keywords to the exceptions list of
the checkpatch.pl script, to prevent error message "Macros with multiple
statements should be enclosed in a do - while loop". Otherwise it is not
possible to build a struct or union with a macro.
