Exit code of cat is not specified. So cat is enough to just warn user,
but we have to use grep to branch.

Grep should return 2 in case of permission denied, but it's not stable
across implementations - grep can return 0 if patter is found and 1 in
all other cases.

So I just choose the most reliable solution.

I plan to file infrastructure bug to clarify it. Tests shouldn't run as
root in any case.
