yate: revert uclibc++ commit

This reverts commit b8b9818a13.

In hindsight I have to admit I did not correctly understand the
implications of the uclibc++.mk include.

The include allows a package to follow the user's choice regarding which
C++ library should be the standard. Linking against uClibc++ instead of
libstd++ is not a problem when running musl (which is what I had
incorrectly assumed), as both C++ libs are separate packages. And
uClibc++ is a lot smaller than libstd++, which is probably why it is
even the default C++ lib on OpenWrt currently.
