Slackware ARM: add a Linux_aarch64-gcc3 entry to Firefox's bundled
Widevine manifest. Run from the top of the Firefox source tree.

Mozilla's update server offers no Widevine for aarch64 Linux, so
media.gmp-widevinecdm.forceInstall seeds the plugin from this entry, and
media.gmp-widevinecdm.force-chromium-update then replaces the URL and
version with whatever Google's component updater currently serves.

The values below are only a seed: they never need updating. They are
used directly only if Google's redirect fails.
