Conversion from FileMode to FileType is incorrect.

[bspot]

The From<FileMode> implementation for FileType uses the bitflags contains function to check the file mode against the FileMode enum members, e.g. mode.contains(FileMode::DIR).

However, the file modes are not flags - their set bits overlap.

As a result, the FileType will be wrong for certain file modes.

Example:

The file is a socket, file mode 0xC000 == 1100000000000000.

The first test is against FileMode::DIR which is 0x4000 == 100000000000000.

Since all set bits in 110000000000000 are also set in 1000000000000000, the check succeeds and the file type is set to FileType::Dir.
