Eliminate 'ISO C90 does not support long long' compiler pedantic warning

Long (32-bit) type is sufficient to represent time delta (duration)
in test_stack.

* tests/test_stack.c (get_msecs): Change return type from long long
to unsigned long (use lowest 32 bits of time value).
* tests/test_stack.c (main): Change type of start_time local variable
to unsigned long; remove redundant type cast.
