core: Fix creating 128-bit uuid_t based on GATT service

sdp_uuid128_create() gets the 128-bit UUID on big-endian (human-readable
format) byte order. Service declaration attributes puts the UUIDs in the
attribute value field using little endian order. This patch converts the
128-bit UUID from little-endian to big-endian before creating uuid_t.
