Inspect: Add error if no results (#19476)

When no results match or another error occurs, add an error to the stream. Keep the "inspect-input.txt" as the only thing in the zip for reference.

Example:

```
λ mc support inspect --airgap myminio/testbucket/fjghfjh/**
mc: Using public key from C:\Users\klaus\mc\support_public.pem
File data successfully downloaded as inspect-data.enc

λ inspect inspect-data.enc
Using private key from support_private.pem
output written to inspect-data.zip
2024/04/11 14:10:51 next stream: GetRawData: No files matched the given pattern

λ unzip -l inspect-data.zip
Archive:  inspect-data.zip
  Length      Date    Time    Name
---------  ---------- -----   ----
      222  2024-04-11 14:10   inspect-input.txt
---------                     -------
      222                     1 file

λ
```

Modifies inspect to read until end of stream to report the error.

Bonus: Add legacy commandline params
