builtin terminfo: add custom 'query-os-name'

Inspired by Kitty's 'kitty-query-os_name'. Notable changes:

* Drop kitty prefix
* os_name -> os-name
* Use "uname -s" without any transformations (e.g. no lower-casing)

    $ ./utils/xtgettcap query-os-name

capability name, foot's reply is identical to what `tigetstr()` would
have returned.
In addition to queries for terminfo entries, the `query-os-name` query
will be answered with a response of the form `uname=$(uname -s)`,
where `$(uname -s)` is the name of the OS foot was compiled for.
