add support for clipboard_target config option

Default behaviour of `xclip` is to copy into the `primary` selection.
Default behaviour of `wl-copy` is to copy into the `clipboard`.

This commit introduces a new config option called `clipboard_target`
that:
 - allows disabling the copy to any clipboard entirely
 - enforce copy to `primary` (i.e. for `wl-copy`)
 - enforce copy to `clipboard` (i.e. for `xclip`)
