build-sys: reverse shlibs installation

[kzak@redhat.com:

Unfortunately, libtool does not provide a way how to install real
libraries to /lib and devel libs (symlinks) to /usr/lib. We have
to use install hooks to move these files.

Currently we install to /lib and move devel files to /usr/lib. This
concept is wrong, because the libdir= in .la libtool files must to
match with the place where we install the devel .so libs. It means we
have to install everything to /usr/lib and then move (by install hook)
the real .so libs to /lib.

This change is necessary to fix "make install", otherwise the install
process will not work in clean change root. ]
