s390/vdso: Drop '-shared' from KBUILD_CFLAGS_64 



When clang's -Qunused-arguments is dropped from KBUILD_CPPFLAGS, it
points out that there is a linking phase flag added to CFLAGS, which
will only be used for compiling

  clang-16: error: argument unused during compilation: '-shared' [-Werror,-Wunused-command-line-argument]

'-shared' is already present in ldflags-y so it can just be dropped.

Fixes: 2b2a2584 ("s390/vdso: Use $(LD) instead of $(CC) to link vDSO")
