Sergey Biryukov 26a276db6f Filesystem API: Make sure to only call fread() on non-empty files in PclZip::privAddFile(). ...

This avoids a fatal error on PHP 8 caused by passing a zero value to `fread()` as the `$length` argument, which must be greater than zero.

This commit also amends the previous solution for similar issues elsewhere in the file to ensure consistent type for string values, instead of changing the type from `string` to `bool` when trying to read from an empty file.

Follow-up to [50355].
