Add suspicious_open_options lint.
Checks for the suspicious use of OpenOptions::create()
without an explicit OpenOptions::truncate().

create() alone will either create a new file or open an
existing file. If the file already exists, it will be
overwritten when written to, but the file will not be
truncated by default. If less data is written to the file
than it already contains, the remainder of the file will
remain unchanged, and the end of the file will contain old
data.
In most cases, one should either use `create_new` to ensure
the file is created from scratch, or ensure `truncate` is
called so that the truncation behaviour is explicit.
`truncate(true)` will ensure the file is entirely overwritten
with new data, whereas `truncate(false)` will explicitely
keep the default behavior.

```rust
use std::fs::OpenOptions;

OpenOptions::new().create(true).truncate(true);
```

Change lint name to seek_to_start_instead_of_rewind
- This name makes more sense and highlights the issue
