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. Signed-off-by: Petr Štetiar <ynezz@true.cz>
