make `script/godep-restore.sh` more verbose

[concaf]

Hi,

It would be of great help if script/godep-restore.sh would return more verbose output, since restoring the godeps takes quite some time, and getting a verbose output of what is happening when will be of great help.

@containscafeine since #314 is closed, should we close this too?
