Since glibc 2.28, `<sys/types.h>` no longer includes
`<sys/sysmacros.h>`, which provides these macros,
so we have to explicitly import the latter, too, to fix the following
build problems:
flow/Platform.cpp: In function 'void getDiskStatistics(const string&, uint64_t&, uint64_t&, uint64_t&, uint64_t&, uint64_t&, uint64_t&)':
