[PATCH v3 21/24] update-index.c: rewrite index when index-version is given

[Thomas Gummerer <t.gummerer@gmail.com>]

Make update-index always rewrite the index when a index-version
is given, even if the index already has the right version.
This option is used for performance testing the writer and
reader.
