package/{fmc,fmlib}: change repository location

Now that Freescale has been wholly swallowed into NXP, the public-facing
git repositories that were hosting those two packages are no longer
available.

Fortunately, they had been mirrored on Code Aurora forge (a Linux
Foundation project, so relatively stable and trustworthy), which has the
tags we need, and that generates the exact same archives.
