Fix CI

Replace `docsrs` cfg with `libloading_docs`

`docsrs` is a commonly used `cfg` identifier. `libloading`'s
implementation is written in such a way that it cannot compile with this
cfg set, but is still able to produce documentation. This is done so
that the documentation is naturally covering all platform-specific
details in a single page, without users having to e.g. switch between
Windows® and Linux when reading the documentation on `docs.rs`.

The downstream crates may accidentally set this `cfg` for `rustc`
invocations as well, which can then cause them to fail to build, for no
good reason!

Using a cfg specific to a crate (e.g. `libloading_docs`)
more accurately reflects the purpose of this cfg and avoids these
problems altogether.
