x86_64: install unstripped copies of compat vdso on disk
This keeps an unstripped copy of the vDSO images built before they are
stripped and embedded in the kernel. The unstripped copies get installed
in $(MODLIB)/vdso/ by "make install" (or you can explicitly use the
subtarget "make vdso_install"). These files can be useful when they
contain source-level debugging information.
