refactor(nk_widget_text): code for X and Y alignment now looks the same

Small refactor in nk_widget_text that makes the code look the same
for X and Y axis alignment. Before it was unconditionally setting
the label.y/.h values for NK_TEXT_ALIGN_TOP, instead of doing it
inside of the branch (unlike the other axis), which was quite
confusing and probably the reason why the bug existed here
in the first place (see previous commit for reference)
