eal: fix uuid header dependencies

Add the dependent header files explicitly, so that the user just needs
to include the 'rte_uuid.h' header file directly to avoid compile error:
 (1). rte_uuid.h:97:55: error: unknown type name ‘size_t’
 (2). rte_uuid.h:58:2: error: implicit declaration of function ‘memcpy’
