Use PRIu32 and PRIx32 format specifiers to fix warnings

Browse Source 
When using "%d" or "%x" with uint32_t types, arm-none-eabi-gcc reports
warnings like below:

-- >8 -- >8 -- >8 -- >8 -- >8 -- >8 --

In file included from lfs.c:8:
lfs_util.h:45:12: warning: format '%d' expects argument of type 'int', but argument 4 has type 'lfs_block_t' {aka 'long unsigned int'} [-Wformat=]
     printf("lfs debug:%d: " fmt "\n", __LINE__, __VA_ARGS__)
            ^~~~~~~~~~~~~~~~
lfs.c:2512:21: note: in expansion of macro 'LFS_DEBUG'
                     LFS_DEBUG("Found partial move %d %d",
                     ^~~~~~~~~
lfs.c:2512:55: note: format string is defined here
                     LFS_DEBUG("Found partial move %d %d",
                                                      ~^
                                                      %ld

-- >8 -- >8 -- >8 -- >8 -- >8 -- >8 --

Fix this by replacing "%d" and "%x" with `"%" PRIu32` and `"%" PRIx32`.
