perf tools: Do not fail in case of empty HOME env variable
Currently we fail in the following case:
$ unset HOME
$ ./perf record ls
$ echo $?
255
It's because the config code init fails due to a missing HOME variable
value. Fix this by skipping the user config init if there's no HOME
variable value.
