[klibc] stat: Make all stat calls wrappers for statx()
fstat(), fstatat(), lstat(), and stat() don't have direct replacements
that use 64-bit time fields on 32-bit architectures and on mips64.
Instead, we have to use the statx() system call which uses a different
buffer structure.
In preparation for using 64-bit time everywhere:
- Add a statx() system call wrapper
- Replace the architecture-dependent struct stat definitions
with a sensible klibc-specific definition
- Make fstatat() call statx() and convert the returned struct statx
to struct stat
- Make {f,l,}stat() wrappers for fstatat()
