dashboard/config/linux: disable CONFIG_STACKPROTECTOR for KMSAN
Linux v6.4-rc1 built with Clang versions <= 16 with stack protector
enabled panic with the following stack trace:
Kernel panic - not syncing: stack-protector: Kernel stack is corrupted in: start_kernel+0xd8a/0xd90
CPU: 0 PID: 0 Comm: swapper/0 Not tainted 6.3.0-rc1-00042-g9ea7e6b62c2b-dirty #106

https://github.com/ClangBuiltLinux/linux/issues/1815 describes the
problem, which is fixed on the Clang side
(https://reviews.llvm.org/D147975), but before the fix reaches syzbot
we'll have to keep the stack protector disabled.
