theme: the busy spinner is its own colour (tab_status_spinner)

It was drawn in tab_status_busy, the colour of the words it sits beside, which
made one decision out of two. The words have to stay readable at a glance and
a mark does not: a theme may well want the glyph loud and the text calm -- or
the text in the accent and the mark a quiet dot -- and with one entry neither
is available without moving both.

Unset it follows tab_status_busy, derived after it and from whatever that
resolved to, named or derived, so nothing changes for anyone who does not ask
and no theme in contrib needs a line. `--dump-theme` writes both, like every
other colour the compositor draws.
