[PATCH v6 2/3] tests: Avoid Test Failure in erofs for label length

Recently, mkfs.erofs began to enforce that the file system
label is 15 characters or less (exluding NULL terminator).
This causes the current erofs test in GRUB to fail. Reduce
the test label used to fit in this limit allowing the test
to work as expected.
