index: don't right-pad paths when writing compressed entries

Our code to write index entries to disk does not check whether the
entry that is to be written should use prefix compression for the path.
As such, we were overallocating memory and added bogus right-padding
into the resulting index entries. As there is no padding allowed in the
index version 4 format, this should actually result in an invalid index.

Fix this by re-using the newly extracted `index_entry_size` function.
