Include header platform-specific/platform.h at end of dtls_config.h

The new header platform-specific/platform.h contains Contiki-specific
settings such as sizes of memory pools and includes target-specific
definitions. Previously, this has been done in dtls_config.h, but as
autoreconf creates a new dtls_config.h.in, these adjustments were
lost.
