[PATCH 3/3] Kbuild: rename HAVE_CC_STACKPROTECTOR config variable

[Masahiro Yamada]

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.
