Description

is_e2fsprogs_feature_supp() tests if the -E options are supported by e2fsprogs,
by running mke2fs on a small tmp image with 100 blocks.
However mke2fs always fails:

mke2fs 1.47.0-wc3 (22-Jun-2023)
Discarding device blocks: done                            
Creating filesystem with 100 1k blocks and 8 inodes

Allocating group tables: done                            
Writing inode tables: done                            
ext2fs_mkdir: Could not allocate inode in ext2 filesystem while creating /lost+found

mke2fs only creates 8 inodes for this case, which is not enough.
