[PATCH 2/4] Makerules: Remove lib-version, $(subdir-version)

[Florian Weimer <fweimer@redhat.com>]

Also clarify that the “versioned” term refers to the soname, not the glibc
version (which also ends up in the installed file name).

I verified on x86_64-linux-gnu that “make install” produces the same
files.
