Subject: perf ui browser: Fix segfault caused by off by one handling END key

perf ui browser: Fix segfault caused by off by one handling END key

$ perf record ls
$ perf report

Press 'down enter end'

Result:

Program received signal SIGSEGV, Segmentation fault.

The UI browser, used on a argv array would access past the end of the
array on SEEK_END because it wasn't using 'nr_entries - 1', fix it.
