largefiles: add copytostore() fstandin argument to replace readstandin() (API)

copyalltostore(), only one caller of copytostore(), already knows
standin file name of the target largefile. Therefore, passing it to
copytostore() is more efficient than calculating it in copytostore()
or readstandin().
