lib/fonts: Fix visiblity of SUN12x22 and TER16x32 if DRM_PANIC

When CONFIG_FONTS ("Select compiled-in fonts") is not enabled, the user
should not be asked about any fonts.  However, when CONFIG_DRM_PANIC is
enabled, the user is still asked about the Sparc console 12x22 and
Terminus 16x32 fonts.

Fix this by moving the "|| DRM_PANIC" to where it belongs.
Split the dependency in two rules to improve readability.
