[Tarantool-patches] [PATCH luajit] codehealth: fix sign extension in sysprof counters

[Maksim Kokryashkin via Tarantool-patches <tarantool-patches@dev.tarantool.org>]

The `setnumfield` function takes `int64_t` as an argument.
Profile counters used to have the `uint64_t` type before
this patch, which could lead to issues with sign extension.
Now their type is `int64_t`, so they correspond to the
`setnumfield` argument type.
