lakitu: Update kernel ebuild to use INIT_STACK_ALL_ZERO

Original INIT_STACK_ALL(0xAA) is very aggressive, and maybe
result more kernel crash in production for today's software
when upgrade. Make it INIT_STACK_ALL_ZERO to strike a balance
between security and software backwards compatiblity, which will
result to less kernel crash since most developers assume compiler
will help them initialize stack variables to zero though it is a
misconception.

BUG=b/169936557
TEST=presubmit
RELEASE_NOTE=Backported INIT_STACK_ALL_ZERO to replace INIT_STACK_ALL.
