[LTP] [PATCHv2] logrotate: fix permission issue for test2

[Petr Vorel]

Hi Po-Hsu,

> When running this logrotate test on Ubuntu, this test will fail with:
>   logrotate_tests 2 TINFO: sleep 1 min to wait for rotating logs
>   logrotate_tests 2 TFAIL: [ -f /var/log/tst_largelogfile.1.gz ] failed unexpectedly
>   logrotate_tests 2 TFAIL: Failed to create a compressed file

> Look more closely to what this test is trying to do we will see there

> 1. "include /etc/logrotate.d"
> This will rotate other log files defined here, since we are just testing
> the log rotation capability I think there is no need to rotate log files
> other than the testfile itself.

BTW (for next time): I would have separated these 2 changes into 2 commits.

Kind regards,
Petr
