ci: crio: Trail '\r' from exec_host() output

Browse Source 
We've faced this as part of the CI, only happening with the CRI-O tests:
```
 not ok 1 Test readonly volume for pods
 # (from function `exec_host' in file tests_common.sh, line 51,
 #  in test file k8s-file-volume.bats, line 25)
 #   `exec_host "echo "$file_body" > $tmp_file"' failed with status 127
 # [bats-exec-test:38] INFO: k8s configured to use runtimeclass
 # bash: line 1: $'\r': command not found
 #
 # Error from server (NotFound): pods "test-file-volume" not found
```

I must say I didn't dig into figuring out why this is happening, but we
may be safe enough to just trail the '\r', as long as all the tests keep
passing on containerd.
