Subject: [PATCH 2/3] kconfig: tinyconfig: remove stale stack protector fixups

Prior to commit 2a61f4747eea ("stack-protector: test compiler
capability in Kconfig and drop AUTO mode"), the stack protector
was configured by the choice of NONE, REGULAR, STRONG, AUTO.

tiny.config needed to explicitly set NONE because the default
value of choice, AUTO, did not produce the tiniest kernel.

Now that there are only two boolean symbols, STACKPROTECTOR
and STACKPROTECTOR_STRONG, they are naturally disabled by
"make allnoconfig", which "make tinyconfig" is based on.
Remove unnecessary lines from the tiny.config fragment file.
