Increase the default 32-bit build frame size warning limit to 1280 bytes

That was already the limit with KASAN enabled, and the 32-bit x86 build
ends up having a couple of drm cases that have stack frames _just_ over
1kB on my allmodconfig test.  So the minimal fix for this build issue
for now is to just bump the limit and make it independent of KASAN.

[ Side note: XTENSA already used 1.5k and PARISC uses 2k, so 1280 is
  still relatively conservative ]
