selftests/net: have `gro.sh -t` return a correct exit code

[ Upstream commit 784e6abd99f24024a8998b5916795f0bec9d2fd9 ]

Modify gro.sh to return a useful exit code when the -t flag is used. It
formerly returned 0 no matter what.

Tested: Ran `gro.sh -t large` and verified that test failures return 1.
