[Minor] Limit CIDv1 detection to 128 bytes

As requested by @vstakhov in https://github.com/rspamd/rspamd/pull/4310#pullrequestreview-1148226107, try to limit the performance impact of this regular expression. However, given that there does not seem to be a hard limit for CIDv1s in IPFS itself, using an hashing algorithm with large output my permit miscreants to get around this rule.
