fix: Correct entry_size field for result entries

The entry_size field in result entries created by ccache 4.5 are off by
one. Fix this by properly accounting for the new format_ver field in
result payload data.

Note: This bug only affects the recompression feature (-X/--recompress)
and not other ccache usage.

Closes #965.
