Bug#950959: Signed grub-efi binaries missing jfs support

[Steve McIntyre]

Source: grub2
Version: 2.02+dfsg1-20
Severity: important

Hi,

We've just found a bug when testing the 10.3 point release: our signed
Grub binaries don't include support for jfs. Easily fixed, and maybe
worth doing a stable upload too to add this.

It's currently possible to install a system with jfs on root that will
then fail on first boot, which is not great. :-/
