Log Message:
lint: only convert the right operand of '<<' or '>>' in traditional C

Traditional C says: "Then the right operand is converted to int".

C90 dropped that sentence, probably because it didn't have any effect on
the result or the conditions for undefined behavior.

To stick to the wording of the specification, also convert UINT to INT.

While here, fix the call to 'convert'.  The first argument being 'CVT'
means that the conversion comes from a cast-expression instead of an
implicit conversion.  This prevents warnings for 'uint64_t << uint64_t'.
Keeping this unnecessary conversion in C90 or later would have generated
warnings for the functions at the bottom of msg_132.c.
