Rae Moar 887d85a073 kunit: fix bug in debugfs logs of parameterized tests
Fix bug in debugfs logs that causes individual parameterized results to not
appear because the log is reinitialized (cleared) when each parameter is
run.

Ensure these results appear in the debugfs logs, increase log size to
allow for the size of parameterized results. As a result, append lines to
the log directly rather than using an intermediate variable that can cause
stack size warnings due to the increased log size.

Here is the debugfs log of ext4_inode_test which uses parameterized tests
before the fix:

     KTAP version 1

     # Subtest: ext4_inode_test
     1..1
 # Totals: pass:16 fail:0 skip:0 total:16
 ok 1 ext4_inode_test

As you can see, this log does not include any of the individual
parametrized results.

After (in combination with the next two fixes to remove extra empty line
and ensure KTAP valid format):

 KTAP version 1
 1..1
     KTAP version 1
     # Subtest: ext4_inode_test
     1..1
        KTAP version 1
         # Subtest: inode_test_xtimestamp_decoding
         ok 1 1901-12-13 Lower bound of 32bit < 0 timestamp, no extra bits
         ... (the rest of the individual parameterized tests)
         ok 16 2446-05-10 Upper bound of 32bit >=0 timestamp. All extra
     # inode_test_xtimestamp_decoding: pass:16 fail:0 skip:0 total:16
     ok 1 inode_test_xtimestamp_decoding
 # Totals: pass:16 fail:0 skip:0 total:16
 ok 1 ext4_inode_test
