py/profile: Fix printing lineno in frame objects.

The argument corresponding to a `%q` specifier must be of type `qstr`, not
a narrower type like `int16_t`.  Not ensuring this caused an assertion
error on one Windows x64 build.

The argument corresponding to a `%d` specifier must be of type `int`, not a
potentially-wider type like `mp_uint_t`.  Not ensuring this prevented the
function name from being printed on the unix nanbox build.
