Change confusing check discovered while working on HCL color wheel:

COLOR widgets never get created with UI_GRAD_V_ALT values. This is
intended for HSVCUBE color sliders only so reverting this to old value
before it was substituted with a define, which was -1.

There's one case where COLOR buttons get defined with a1 value different
than -1 which is in ui_def_but_rna. There the step value of the RNA
property is used. However, that meant that if step equaled to 9, which
is UI_GRAD_V_ALT value (unlikely) or if UI_GRAD_V_ALT was changed to 10
in future, or we added check for e.g. UI_GRAD_L_ALT which is 10 in HCL
branch, color widget would not get a color selection menu spawned.
