tools: Add additional SYM_*() stubs to linkage.h

Similar to commit f8d92fc527ff ("selftests: vDSO: fix include order in
build of test_vdso_chacha") add SYM_DATA_START, SYM_DATA_START_LOCAL, and
SYM_DATA_END stubs to tools/include/linux/linkage.h so that the proper
macros can be used within the kernel's vdso code as well as in the
vdso_test_chacha selftest.

This is due to kernel include/linux/limits.h being included instead of
libc's limits.h.

This is because directory include/ is added through option -isystem so
it goes prior to glibc's include directory.

Replace -isystem by -idirafter.

But this implies that now tools/include/linux/linkage.h is included
instead of include/linux/linkage.h, so define a stub for
SYM_FUNC_START() and SYM_FUNC_END().

memblock tests: include export.h in linkage.h as kernel dose

In kernel code, linkage.h includes export.h. Let's sync with kernel.

This is a preparation for move init.h in common include directory.
