baylibre-acme: Fix a compiler warning.

Use PRIu64 to avoid the following compiler warning:

    CC       src/hardware/baylibre-acme/gpio.lo
  protocol.c: In function 'bl_acme_set_shunt':
  protocol.c:341:2: warning: format '%llu' expects argument of type 'long long unsigned int', but argument 3 has type 'uint64_t' [-Wformat=]
    g_fprintf(fd, "%llu\n", MOHM_TO_UOHM(shunt));
    ^
