selftests/mount_setattr: increase tmpfs size for idmapped mount tests
The mount_setattr_idmapped fixture mounts a 2 MB tmpfs at /mnt and then
creates a 2 GB sparse ext4 image at /mnt/C/ext4.img. While ftruncate()
succeeds (sparse file), mkfs.ext4 needs to write actual metadata blocks
(inode tables, journal, bitmaps) which easily exceeds the 2 MB tmpfs
limit, causing ENOSPC and failing the fixture setup for all
mount_setattr_idmapped tests.
This was introduced by commit d37d4720c3e7 ("selftests/mount_settattr:
ensure that ext4 filesystem can be created") which increased the image
size from 2 MB to 2 GB but didn't adjust the tmpfs size.
Bump the tmpfs size to 256 MB which is sufficient for the ext4 metadata.
Fixes: d37d4720c3e7 ("selftests/mount_settattr: ensure that ext4 filesystem can be created")
