Free after getline(), even if fail, and catch eof() on el9

getline() allocates the space for the return value even if there is an
error, so when it returns an error, we still have to free() it.

In el9, when reading stdin we will get errno=0 returned (no error) when
we hit the end of stdin. This behavior is different from el7/8. We don't
want to throw an error here to avoid failing the test, since it doesn't.
