s390/vdso: Drop unused '-s' flag from KBUILD_AFLAGS_64
When clang's -Qunused-arguments is dropped from KBUILD_CPPFLAGS, it
warns:
clang-16: error: argument unused during compilation: '-s' [-Werror,-Wunused-command-line-argument]
The compiler's '-s' flag is a linking option (it is passed along to the
linker directly), which means it does nothing when the linker is not
invoked by the compiler. The kernel builds all .o files with '-c', which
stops the compilation pipeline before linking, so '-s' can be safely
dropped from KBUILD_AFLAGS_64.
