rev-branch-cache: stop truncating cache file

Truncating the file prevent the safe use of mmap. So instead of overwrite the
existing data. If more than 20% of the file is to be overwritten, we rewrite the
whole file instead.

Such whole rewrite is done by replacing the old one with a new one, so mmap of
the old file would be affected.

This prepare a more aggressive use of mmap in later patches.
