Missing references to libpetsc.so in libpetscksp.so

[Satish Balay]

You might want to check the code for
PetscInitialize_DynamicLibraries() in src/sys/dll/reg.c

Part of the issue is - on Mac libpetscksp.dylib is linked in with
libpetsc.dylib [otherwise the dylibs can't be created] ..etc - but not
on linux.
