file-systems: read-partition-{uuid,label} don't swallow ENOENT & co.

Previously, (read-partition-uuid "/does/not/exist") would return #f. With this change, a 'system-error exception is raised as expected. * gnu/build/file-systems.scm (ENOENT-safe): Clarify docstring. (partition-field-reader): Remove use of 'ENOENT-safe'. (partition-predicate): Wrap READER in 'ENOENT-safe'.
