init: reduce PARTUUID min length to 1 from 36
Reduce the minimum length for a root=PARTUUID= parameter to be considered valid from 36 to 1. EFI/GPT partition UUIDs are always exactly 36 characters long, hence the previous limit. However, the next patch will support DOS/MBR UUIDs too, which have a different, shorter, format. Instead of validating any particular length, just ensure that at least some non-empty value was given by the user. Also, consider a missing UUID value to be a parsing error, in the same vein as if /PARTNROFF exists and can't be parsed. As such, make both error cases print a message and disable rootwait. Convert to pr_err while we're at it.
