add capctime flag to camput

I can recreate the file, set the modification time, but can't forge creation
time, thus cannot recreate the exact same uploaded file twice.
This change targets this problem.

As this is a very rarely used flag, this is enabled only if the CAMLI_DEBUG
environment variable is true - such as the other "gross" options
(statcache, sqlitecache...).
