colorize: only emit osc8 if [general].enable-osc8=true
Some old versions of less do not handle OSC 8 escape sequences. Even if
aerc's embedded terminal is configured to handle them, less corrupts
them making the output unreadable.
8;id=colorize-1;https://foobar.com/stuff/https://foobar.com/stuff/
When [general].enable-osc8 is set to false (its default value) do not
attempt to generate OSC 8 sequences with the built-in colorize filter.
These sequences would be stripped out anyway.
