block: Improve some block-commit, block-stream error messages
block-commit defaults @base-node to the deepest backing image. When
there is none, it fails with "Base 'NULL' not found". Improve to
"There is no backing image".
block-commit and block-stream reject a @base argument that doesn't
resolve with "Base 'BASE' not found". Commit 6b33f3ae8b "qemu-img:
Improve commit invalid base message" improved this message in
qemu-img. Improve it here, too: "Can't find '%s' in the backing
chain".
QERR_BASE_NOT_FOUND is now unused. Drop.
