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

Browse Source 
Similar to commit f8d92fc527 ("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.
