Factor shell script size command into configure script

Commit 149839c5391e9a93 introduced a small behavior regression as a drawback
for a better portability. repo-add now includes the approximate size (to the
nearest KB) rather than an exact size due to the switching of the du command
to a more portable form. Instead of sacrificing the exact size, use
configure to help us determine a valid command to acquire our filesize and
place it in the sync database.
