lib/vsprintf: Move integer format types to the top 

Move the format types for 64-bit integers and configurable size integers
to the top, so they're next to the other integer format types.  While at
it, add the missing format types for s32 and u32.

unsigned long long %llu or %llx

u32 %u or %x
s64 %lld or %llx

If <type> is dependent on a config option for its size (e.g., sector_t,
blkcnt_t) or is architecture-dependent for its size (e.g., tcflag_t), use a
format specifier of its largest possible type and explicitly cast to it.
Example:
printk("test: sector number/total blocks: %llu/%llu\n",
(unsigned long long)sector, (unsigned long long)blockcount);
Reminder: sizeof() result is of type size_t.
Raw pointer value SHOULD be printed with %p. The kernel supports
the following extended format specifiers for pointer types:
