Calle Wilund 59c87025d1 commitlog::read_log_file: Check for eof position on all data reads ...

Fixes #24346

When reading, we check for each entry and each chunk, if advancing there
will hit EOF of the segment. However, IFF the last chunk being read has
the last entry _exactly_ matching the chunk size, and the chunk ending
at _exactly_ segment size (preset size, typically 32Mb), we did not check
the position, and instead complained about not being able to read.

This has literally _never_ happened in actual commitlog (that was replayed
at least), but has apparently happened more and more in hints replay.

Fix is simple, just check the file position against size when advancing
said position, i.e. when reading (skipping already does).

v2:

* Added unit test

Closes scylladb/scylladb#27236
