build(vim-patch): n/a docs from 9.0.1481, keep hunks without header

switch/case and goto labels v9.0.1481 and similar patches
from auto-N/A.
Blacklist as much as possible to auto-N/A later crypt patches.

Hunks without header in "*.h" is valid if only littered with #ifdefs
or change is isolated to 1st line
but "src/feature.h" should be mostly N/A
after Nvim removed "FEAT_" guards.
Wonder if certain patches with only "*.h" changes were mistakenly
marked N/A.
