sys-fs/e2fsprogs: Backport prezeroed storage hint to mke2fs

Backport commit /bd2e72c5c5521b561d20a881c843a64a5832721a to e2fsprogs.
This allows mke2fs to omit zeroing out inode tables on storage devices
that can already be considered as 'pre-zeroed', in turn, saving a lot
of otherwise zeroed out space on thinly provisioned filesystems
(eg. loop devices, logical volumes) and time taken during filesystem
creation.

BUG=b:200640037
TEST=emerge e2fsprogs succeeds.
