objtool: Fix CONFIG_STACK_VALIDATION=y warning for out-of-tree modules
When building a CONFIG_STACK_VALIDATION enabled kernel without the
libelf devel package installed, the Makefile prints a warning:
"Cannot use CONFIG_STACK_VALIDATION, please install libelf-dev, libelf-devel or elfutils-libelf-devel"
But when building an out-of-tree module, the warning doesn't show.
Instead it tries to use objtool, and the build fails with:
/bin/sh: ./tools/objtool/objtool: No such file or directory
Make sure the warning and the disabling of objtool occur in all cases,
by moving the CONFIG_STACK_VALIDATION checks outside the 'ifeq
($(KBUILD_EXTMOD),)' block in the Makefile.
