Subject: [PATCH] lib: Fix timeval_cmp_margin for 32-bit systems

The test suite compares times with seconds values of -INT_MAX and
INT_MAX. The result of this comparison does not fit in a value of
type int and so the test suite fails on 32-bit systems where time_t
is an int. To fix this, calculations on seconds values are done
using long long integers.
