SV and Goose publisher: remove libiec61850_platform_includes.h include

Any application including goose_publisher.h or sv_publisher.h from installed headers
(/usr/include/libiec61850) fail to build due to missing libiec61850_platform_includes.h
internal header.

libiec61850_platform_includes.h was removed from installed headers (API_HEADERS)
by commit [1].
