Subject: [PATCH] tests: add test for symlink extent

Long symlinks with the EXT4_EXTENTS_FL set may have been created at
one time due to the EXTENTS_FL being inherited from the parent dir.
While the original cause of such symlinks has been fixed in the
upstream kernel commit 2dc6b0d48ca0599837df21b14bb8393d0804af57,
such symlinks may still exist in the wild.

Add a test image that includes an extent symlink for sanity checks.
