git submodule update occasionally fails.

I've sometimes seen the following error when I tried to build this module by using meta-renesas.

 | DEBUG: SITE files ['endian-little', 'bit-64', 'arm-common', 'arm-64', 'common-linux', 'common-glibc', 'aarch64-linux', 'common']

According to the freedesktop's wiki page, their git repositories had been moved to gitlab.fd.o, which is hosted on Google Cloud Platform. The former repository server is still working but seems unstable a little compared to gitlab.fd.o.

Some recipes in yocto project had already switched their referring repository url, like this;

• https://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/meta/recipes-multimedia/gstreamer/gst-examples_git.bb?id=100a30bdb11738e6ce7d1fe224a6da9e9829ce3e

I suggest you'd better switch submodule's url.
