[PATCH 4/6] ftracetest: Use logfile name supported by busyboxs mktemp

From: Steven Rostedt

When I run the ftracetest in a busybox docker container, I saw
following error. Make the logfile template to comply with busybox's
mktemp. It also keep the logfiles under the logs directory.

# /linux/tools/testing/selftests/ftrace/ftracetest
=== Ftrace unit tests ===
mktemp: unrecognized option `--tmpdir=/linux/tools/testing/selftests/ftrace/logs/20141106-003624/'
BusyBox v1.22.1 (2014-05-22 23:22:11 UTC) multi-call binary.

Usage: mktemp [-dt] [-p DIR] [TEMPLATE]

Create a temporary file with name based on TEMPLATE and print its name.
TEMPLATE must end with XXXXXX (e.g. [/dir/]nameXXXXXX).
Without TEMPLATE, -t tmp.XXXXXX is assumed.

-d Make directory, not file
-q Fail silently on errors
-t Prepend base directory name to TEMPLATE
-p DIR Use DIR as a base directory (implies -t)
-u Do not create anything; print a name

Base directory is: -p DIR, else $TMPDIR, else /tmp

[1] Basic trace file check/linux/tools/testing/selftests/ftrace/ftracetest: line 244: can't create : nonexistent directory
/linux/tools/testing/selftests/ftrace/ftracetest: line 244: can't create : nonexistent directory
[FAIL]
