The device numbers in struct statx may be larger than dev_t

Browse source 
`dev_t` is already 64-bit in glibc, but on some platforms like Alpine
Linux and Android NDK, `makedev` is defined as more than 32-bit (
promoting to `unsigned long long` then left-shifting by 32bit), while
`dev_t` is still 32-bit.
