On kernel with only one out of CONFIG_KPROBE_EVENTS and
CONFIG_UPROBE_EVENTS enabled, 'perf probe -d' causes a segfault because
perf_del_probe_events() calls probe_file__get_events() with a negative
fd.
This patch fixes it by adding parameter validation at the entry of
probe_file__get_events() and probe_file__get_rawlist(). Since they are
both non-static public functions (in .h file), parameter verifying is
required.
v1 -> v2: Verify fd at the head of probe_file__get_rawlist() instead of
checking at call site (suggested by Masami and Arnaldo at [1,2]).

Using tracing_path interface on several places, that more or less
copy the functionality of tracing_path interface.

Showing actual trace event when deleteing perf events is only needed in
perf probe command. But the add functionality itself can be used by
other places. So move the printing code into the cmd_probe().
The output is not changed.

The del_perf_probe_events() does 2 things:
1. find existing events which match to filter
2. delete such trace events from kernel
But sometimes we need to do something with the trace events. So split
the funtion into two, so that it can access intermediate trace events
name using strlist if needed.
