[PATCH v3 3/3] Documentation: update the of_unittest.txt

[Wang Long]

Since the directory "drivers/of/testcase-data" is renamed
to "drivers/of/unittest-data". so we should update the path
in the of_selftest.txt.

When the kernel is built with OF_UNITTEST enabled, the output
dtb is testcases.dtb instead of testcase.dtb, also update it
(s/testcase/testcases/).
