[Fix] Fix re_cache hyperscan file tracking and buffer size

Two fixes for hyperscan cache file handling:

1. Increase hyperscan_cache_file.filename buffer from 64 to 80 bytes
   to accommodate full filenames (64 hex hash + ".hs.unser" = 73 chars)

2. Add rspamd_hyperscan_notice_known() call in re_cache.c after loading
   hyperscan databases. Without this, re_cache files weren't registered
   as "known" and would be deleted by cleanup_maybe() on restart,
   causing unnecessary recompilation.
