== Justification ==
There are some non-POSIX implementations in the test script, which will
generate some noise in the test reports like:
  -e -n [1] Basic trace file check
  -e [PASS]
  -e -n [2] Basic test for tracers
  -e [PASS]

== Fix ==
* 4ce55a9c (selftests/ftrace: Replace \e with \033)
* 37fb665b (selftests/ftrace: Replace echo -e with printf)

These two patches can be cherry-picked into D/E

== Test ==
Tested on a P8 box with Disco, the patched test will print the report in
a proper format:
  [1] Basic trace file check	[PASS]
  [2] Basic test for tracers	[PASS]

== Regression Potential ==
No regression is expected. This patchset just make sure this test comply
with POSIX standard.

  selftests/ftrace: Replace \e with \033
  selftests/ftrace: Replace echo -e with printf
