[sddm-theme/lock screen] Tighten clock and username shadows

This patch tightens the shadows around the clock in the Breeze SDDM theme and lock screen so as to prevent the appearance of a diffuse dark glare that appears around the clock on top of very bright backgrounds.

In addition, it tightens the username/prompt shadows to match the shadows used in desktopcontainment.

Test Plan:
Username shadows, before:

and after:

(the new shadows take after the ones in desktopcontainment)

Before (white background):

After (white background):

Before (Next):
