tools: bpftool: preserve JSON output on errors on batch file parsing 

Before this patch, perror() function is used in some cases when bpftool
fails to parse its input file in batch mode. This function does not
integrate well with the rest of the output when JSON is used, so we
replace it by something that is compliant.

Most calls to perror() had already been replaced in a previous patch,
this one is a leftover.
