    Fix selecting clearing and BCE

    The commit b78c5085f72 changed the st behaviour enabling BCE capability,
    that means erase regions using background color. Problem comes when you
    clear a region with a selection, because in this case the real mode of the
    Glyph is not the value of term.line[y][x], due in drawregion we had enabled
    the ATTR_REVERSE bit.
