package/e2fsprogs: bump version to fix regression

Version 1.46.3 had a regression, which meant the file that would store
the filesystem image had to pre-exist, or mkfs.ext2 would fail to
generate the filesystem:

    mkfs.ext4: No such file or directory while trying to determine
    filesystem size

The regression was fixed upstream, and is now part of the 1.46.4
release, so bump to that release.

Fixes: #14196
Additionally, as noticed by Romain, the defaults settings for generating
"small" filesystems have changed: the inode size has been increased fom
128 to 256 bytes in 1.46.4 [0]. This causes the number of inodes to
diverge slightly from the requested number; instead of 8 more inodes,
there are now 8 fewer than requested.

Adapt our test accordingly.
