ODT export: handle style name of covered cells

This is the export side of commit
1001dbaef4dec2b51c25ed8343bab6910f1219e1 (ODT import: handle style name
of covered cells, 2021-03-19). We already exported the autostyle, but
<table:covered-table-cell> did not refer to it.

This is useful when the covering and the covered table cells have
different border settings.
