Log Message:
tests/lint: fix test for message 132 to be platform-independent

On i386, the test failed because the warning in line 101 was not
generated.  This was because size_t on i386 is unsigned int (see
arch/i386/targparam.h, SIZEOF_TSPEC). The result of the multiplication
had type unsigned int, and message 132 does not trigger for a conversion
from unsigned int to signed int because both types have the same size
(see check_integer_conversion, portable_size_in_bits).

Change the involved type from size_t (which the original code used) to
unsigned long long (which is uint64_t on all platforms supported by
lint), so that the warning is generated on all platforms in the same
way.
