Linux's variant uses the syscall as intended. Redox's variant uses fpath to build a path to pass to fstat from the file descriptor plus the file name. Unlike the syscall, this isn't atomic so the liminal space between fpath/getcwd and fstat is subject to TOCTOU. Beyond fstatat, I moved the stat test to its correct location and added an assert since the output of the test is unchecked. I also added AT_FDCWD which seems to be -100 across Unixes. The other AT_* constants are unimplemented for now.
