cmd/internal/buildid: reject empty id
The loop that makes progress assumes that after matching an id
you should advance len(id) bytes in the file. If id is the empty string,
then it will match and advance 0 bytes repeatedly.
0-byte ids are not really build IDs, so just reject it outright.
Fixes #47852.
