shield Recommended update for shim

SUSE-SLE-SERVER-12-2016-6

The shim bootloader for UEFI secure boot support was updated to the unified version 0.9 between SUSE Linux Enterprise versions (same as SUSE Linux Enterprise 12 SP1). (FATE#318904) This also fixes two bugs: * RSOD comes when you enter and exit from grub commandline (bsc#919675) * StrCpy() could crash fallback.efi due to the under-allocated buffer (bsc#920515)
