The MTE prctl test emits one result from check_basic_read() followed by
one result for each of the seven entries in mte_modes[]. However, the TAP
plan only accounts for the array entries, producing:
# Planned tests != run tests (7 != 8)
Include the basic read check in the plan so that all eight emitted results
are declared.
