fix the size of gotwebd's array of tempfiles used for deltas

Prevents ftruncate() errors due to bogus file descriptors passed from
gotwebd once the repository layer runs out of temporary files to use
for deltas. Have gotwebd open the maximum amount of required temporary
files for now. A proper fix which scales to lower ulimit -n settings can
be implemented later.
