[PATCH v2 2/2] Ext4Pkg: Advertise CSUM_SEED as supported

["Pedro Falcato" <pedro.falcato@gmail.com>]

We had added support for CSUM_SEED but accidentally forgot to advertise
it in gSupportedIncompatFeat. This made it (erroneously) impossible to
mount CSUM_SEED filesystems.

Detected by attempting to mount a relatively new mkfs.ext4'd filesystem.
