deqp-runner is assuming that every dot in the expectation files is a
`DOT` regex character, which usually is not intended.

For bigger files, such as [1], this is causing `RegexSet` to reach its
default size limit without reason. Here is the error message:

```
Error: compiling skips regexes
Caused by:
    0: Parsing regex set
    1: Compiled regex exceeds size limit of 10485760 bytes.
```

Adopted the strategy to detect if an expectation line has another regex
character, such as `*`, to decide whether the `.` should be escaped.
