[LTP] [PATCH] fix the -I option and enable a larger numble to I option

[Zhouping Liu <zliu@redhat.com>]

Hi Garrett,
Please review.
when running a test case with setting -I options a number, it's 
useless. 
e.g  when I run testcase/kernel/mem/hugetlbfs/hugemmap/hugemmap01,
[root@dell-per805-01 hugemmap]# ./hugemmap01 -I 3600 -H /var/hugetlbfs/
hugemmap01    1  TPASS  :  call succeeded
[root@dell-per805-01 hugemmap]# 
the test returned immediately, but no running for 3600 seconds, and other test cases all 
have this problem. I found it was that the variable stop_time in lib/parse_opts.c was integer that's not 
enough large, I changed it to a larger type(long long type), then it was okay, and support a larger number.
