perf python scripting: Append examples to err msg about audit-libs-python

To print syscall names, the audit-libs-python package is required.. If not installed, it prints this error string: # perf script syscall-counts Install the audit-libs-python package to get syscall names. But the package name is different in Ubuntu, mention that in the error message, similar to a error message of util/trace-event-scripting.c: # perf script syscall-counts Install the audit-libs-python package to get syscall names. For example: # apt-get install python-audit (Ubuntu) # yum install audit-libs-python (Fedora) etc.
