Fix logging

[Dirk007]

Added libraries (source) and includes to fix cmaked builds that have NRF_LOG_ENABLED set to 1. Now, logging works.

Fixes in detail:

In file included from /something/nRF5SDK/components/libraries/log/nrf_log_ctrl.h:59,
                 from /something/nRF5SDK/components/ble/peer_manager/gatt_cache_manager.c:64:
/something/nRF5SDK/components/libraries/log/nrf_log_backend_interface.h:54:10: fatal error: nrf_memobj.h: No such file or directory
 #include "nrf_memobj.h"

and it's recursive dependencies (balloc, strfmt, ...)
