f2fs_fs.h: Use standard fixed width integer types

Use uint64_t instead of __u64 in the definitions of the endianness
conversion macros. This patch fixes the following compiler warning:

dir.c: In function ‘f2fs_create’:
dir.c:785:16: warning: format ‘%lx’ expects argument of type ‘long unsigned int’, but argument 12 has type ‘long long unsigned int’ [-Wformat=]
  785 |         MSG(1, "Info: Create %s -> %s\n"
      |                ^~~~~~~~~~~~~~~~~~~~~~~~~
../include/f2fs_fs.h:252:32: note: in definition of macro ‘MSG’
  252 |                         printf(fmt, ##__VA_ARGS__);                     \
      |                                ^~~
