[LTP] [PATCH v3] sched_getattr/sched_getattr01: Add new testcase to test sched_getattr

[Cyril Hrubis]

Hi!
Pushed with following changes:

* TCID changed to match the file name

* Added tst_parse_opts() and TEST_LOOPING()
  (Somehow I've missed that it's missing in the review)

* Added tst_require_root() since the test needs root to change
  scheduller attributes

* Removed newlines from the tst_resm()/tst_brkm() strings

Thanks.
