kernel: Fix KERNEL_STACKPROTECTOR on kernel 4.19

The configuration option was renamed with kernel 4.19 from
CONFIG_CC_STACKPROTECTOR to CONFIG_STACKPROTECTOR adapt the code to set
both options.

CONFIG_STACKPROTECTOR now sets the regular stack protector and
CONFIG_STACKPROTECTOR_STRONG activates the additional protection of more
functions.
