mpers.awk: use stdint.h instead of inttypes.h

As <inttypes.h> is included in files generated by mpers.awk to obtain
definitions of uintNN_t types provided by <stdint.h>, replace the former
header with the latter.

* mpers.awk: Use <stdint.h> instead of <inttypes.h>.
* mpers_test.sh: Update expected output.
