tools: bpftool: fix plain output and doc for --bpffs option
Edit the documentation of the -f|--bpffs option to make it explicit that it dumps paths of pinned programs when bpftool is used to list the programs only, so that users do not believe they will see the name of the newly pinned program with "bpftool prog pin" or "bpftool prog load". Also fix the plain output: do not add a blank line after each program block, in order to remain consistent with what bpftool does when the option is not passed.
