Remove extra ';' in table_of_recent_compares.h

The patch
8b93bbe
introduced an extra ';' two weeks ago.

This causes chromium fuzztest autoroller to fail at the moment:
```
fuzztest/internal/table_of_recent_compares.h:219:79: error: extra ';' after member function definition [-Werror,-Wextra-semi]
  219 |   explicit TableOfRecentlyComparedBuffers(bool compact) : compact_(compact) {};
```
