Kbuild: rename HAVE_CC_STACKPROTECTOR config variable
HAVE_CC_STACKPROTECTOR should be selected by architectures with stack
canary implementation. It is not about the compiler support.
For the consistency with commit 050e9baa9dc9 ("Kbuild: rename
CC_STACKPROTECTOR[_STRONG] config variables"), remove 'CC_' from the
config symbol.
I moved the 'select' lines to keep the alphabetical sorting.
