powerpc: add crtsavres.o to always-y instead of extra-y 

[ Upstream commit 1b1e38002648819c04773647d5242990e2824264 ]

crtsavres.o is linked to modules. However, as explained in commit
d0e628cd81 ("kbuild: doc: clarify the difference between extra-y
and always-y"), 'make modules' does not build extra-y.

For example, the following command fails:

  $ make ARCH=powerpc LLVM=1 KBUILD_MODPOST_WARN=1 mrproper ps3_defconfig modules
    [snip]
    LD [M]  arch/powerpc/platforms/cell/spufs/spufs.ko
  ld.lld: error: cannot open arch/powerpc/lib/crtsavres.o: No such file or directory
