Unit tests for spdk_strtol/spdk_strtoll use hard coded strings for
arithmetic constants (LONG_MIN/MAX etc). These are only valid
on platforms where both long and long long are 64-bit values.
Replace the hardcoded values with strings generated from limits.h.
The tests use values that are outside of the MIN/MAX range, which
cannot be represented as int64_t. These are calculated in two parts
to avoid overflow and recombined as a string.
Verified using the unit tests on two different architectures and with
test code to check that the generated string is the same as the
hardcoded value on x86 Linux. Used a small test program to calculate
+/-30 around each limit value to check carry handling and boundary
conditions.
