crypto: vmx - Align the short log with Makefile cleanups

I notieced the log is not properly aligned:

  PERL drivers/crypto/vmx/aesp8-ppc.S
  CC [M]  fs/xfs/xfs_reflink.o
  PERL drivers/crypto/vmx/ghashp8-ppc.S
  CC [M]  drivers/crypto/vmx/aes.o

Add some spaces after 'PERL'.

While I was here, I cleaned up the Makefile:

 - Merge the two similar rules

 - Remove redundant 'clean-files' (Having 'targets' is enough)

 - Move the flavour into the build command

This still avoids the build failures fixed by commit fd982e33732a
("crypto: vmx - Avoid weird build failures").
