package/gstreamer1/gst1-plugins-bad: needs C++

gst1-plugins-bad needs C++ since switch to meson-package in commit
5d6c408e9535be4b5ba0c8a49215d2d03dcb5cd5:

The following exception(s) were encountered:
Running "/home/autobuild/autobuild/instance-8/output-1/host/bin/microblaze-buildroot-linux-musl-g++ --version" gave "[Errno 2] No such file or directory: '/home/autobuild/autobuild/instance-8/output-1/host/bin/microblaze-buildroot-linux-musl-g++'"

Rewriting the meson.build so it only requires C++ for the modules that
are actually written in C++ is quite complicated, so just let the whole
package depend on C++. Hopefully however this is going to be fixed in
some future release. Therefore, the dependencies for individual modules
are kept as well (even though they're redundant now).
