Deprecates uname_attr and uname_info public methods

distro as well as LinuxDistribution `uname_attr` and `uname_info` public
methods are based on `_parse_uname_content` function which purposely
ignores release information part from `uname -rs` command output on
Linux platforms. This makes it specially designed for distro internals,
and shouldn't be publicly available as stable API.

We'll deprecate these methods in v1.11.0, in order to allow API removals
in the future (e.g. distro v2).

> closes #322
