Fix child-theme/plugin path check when --path contains relative segments

When --path includes .. or . segments (e.g. --path=../mysite/),
WP_CONTENT_DIR retains the unnormalized path, but check_target_directory()
canonicalizes the target_dir before comparing. This mismatch causes
false rejection of valid theme/plugin directories.

Apply canonicalize_path() to both sides of the comparison so paths
with relative segments are resolved consistently.
