[PATCH] checkpatch: add grammatical judgement for total output

[Hu Haowen <src.res@email.cn>]

There lacked a English grammatical identification within the final
output of checkpatch.pl such as the following:

    total: 1 errors, 11 warnings, 4094 lines checked
                  ^

Which violated the rule about the usage of the singular form and the
plural form. Hence fix the issue up and make it output the proper
sentence.
