This check is wrong and would cause the close_range() function being called even when it's not available

Seems a little bit Rich that musl does not implement close_range because
they suspect that the system call itself is a bad idea, so they uhhhh
are considering not implementing a wrapper. Let's just fix the problem
at hand by writing our own wrapper.

this is only used to close non-stdio files in derivation sandboxes. we
may as well encode that in its name, drop the unnecessary integer set,
and use close_range to deal with the actual closing of files. not only
is this clearer, it also makes sandbox setup on linux fast by 1ms each

This:
- Converts a bunch of C style casts into C++ casts.
- Removes some very silly pointer subtraction code (which is no more or
less busted on i686 than it began)
- Fixes some "technically UB" that never had to be UB in the first
place.
- Makes finally follow the noexcept status of the inner function. Maybe
in the future we should ban the function from not being noexcept, but
that is not today.
- Makes various locally-used exceptions inherit from std::exception.

the `*Source` name is a slight misnomer since we do also have a
Source type, but we can probably live with this for time being.
