test-basic: make test compatible with chg
The error codes returned when writing to /dev/full are different after
the first failure with and without '--chg' option. Therefore, this commit
conditionally handles the error codes as appropriate.
Test Plan:
Ran the test 'test-basic.t' with and without '--chg' option.
