Revert "kunit: configs: Enable CONFIG_INIT_STACK_ALL_PATTERN in all_tests"

This reverts commit a571a9a1.

The commit in question breaks kunit for older compilers:

$ gcc --version
 gcc (GCC) 11.5.0 20240719 (Red Hat 11.5.0-5)

$ ./tools/testing/kunit/kunit.py run  --alltests --json --arch=x86_64
 Configuring KUnit Kernel ...
 Regenerating .config ...
 Populating config with:
 $ make ARCH=x86_64 O=.kunit olddefconfig
 ERROR:root:Not all Kconfig options selected in kunitconfig were in the generated .config.
 This is probably due to unsatisfied dependencies.
 Missing: CONFIG_INIT_STACK_ALL_PATTERN=y
