RFR(S): 8175163: [bsd] Fix build after "8005629: javac warnings compiling java.awt.EventDispatchThread..."

[Lindenmaier, Goetz]

Hi

8005629 removed file EventDispatchAccess.java, but did not remove it from the 
list of exported files in FILES_export_macosx.gmk.
http://cr.openjdk.java.net/~goetz/wr17/8175163-macErr3/webrev.01/

Please review this change.

@Florian: With the three changes I now posted I could build on mac.

Best regards,
Goetz.
