killing UNOLIBS_OOO

Hi,

there is needless complexity added to gbuild by having all those "creative"
library naming schemes. One of them is UNOLIBS_OOO which is just like OOOLIBS,
except that they are named a bit different: libfoo.uno.so instead of
libfoolo.so. On dmake/build.pl and esp. with a dmake/build.pl/gbuild mix such a
change would have been needlessly painful because of the many places, were such
a name would show up.

I propose we kill of this needless separation, here is a start (with some more
rationale in the commit msg):

 http://gerrit.libreoffice.org/#/c/2169/

which also serves as a sample. As you see, its relatively simple by now -- the
only additional bookkeeping is in scp2.

If there is no violet opposition to this, I would push this to master and
create a EasyHack to kill of the other UNOLIBS_OOO too.

Any objections? Speak up now or be silent ;)

Best,

Bjoern
