scripts/download.pl: silence can't exec curl warning

When running build in verbose mode `make V=s` we can see a lot of
following warnings when curl is not available in the system:

 Can't exec "curl": No such file or directory at scripts/download.pl line 77.

So lets fix it by redirecting of the stderr to null hole.
