	[ruby/rdoc] test/rdoc/test_rdoc_generator_json_index.rb: Use
	 assert_equal instead of assert.

	It's better because assert_equal prints the values when it fails.

	[ruby/rdoc] test/rdoc/test_rdoc_generator_json_index.rb: pend in
	 test_generate in ppc64le.

	We observed that this test randomly fails in the ruby/ruby Travis ppc64le case.
	This commit is to pend the test_generate if the assertion for the generated
	file's modified time fails in a ppc64le environment.

	Note that I didn't use the word "Travis CI" or Travis CI specific environment variables
	such as `TRAVIS` and `TRAVIS_CPU_ARCH`[1] in the code. Because I wanted to prioritize the
	rdoc's independence from the ruby/ruby.
