sys: cbprintf: Suppress bugprone-sizeof-expression

clang-tidy reports a bugprone-sizeof-expression warning for
sizeof((__v)) when __v is a pointer type. This is a false-positive
in contexts like logging with %p, where using a pointer is
intentional and expected.

Add a NOLINT comment to suppress the warning in static analysis.
