tests/qtest/npcm7xx_rng-test: dump random data on failure
Dump the collected random data after a randomness test failure.
Note that this relies on the test having called g_test_set_nonfatal_assertions() so we don't abort immediately on the assertion failure.

tests/qtest/npcm7xx_rng-test: Disable randomness tests
The randomness tests in the NPCM7xx RNG test fail intermittently but fairly frequently. On my machine running the test in a loop: while QTEST_QEMU_BINARY=./qemu-system-aarch64 ./tests/qtest/npcm7xx_rng-test; do true; done
will fail in less than a minute with an error like: ERROR:../../tests/qtest/npcm7xx_rng-test.c:256:test_first_byte_runs: assertion failed (calc_runs_p(buf.l, sizeof(buf) * BITS_PER_BYTE) > 0.01): (0.00286205989 > 0.01)
(Failures have been observed on all 4 of the randomness tests, not just first_byte_runs.)
It's not clear why these tests are failing like this, but intermittent failures make CI and merge testing awkward, so disable running them unless a developer specifically sets QEMU_TEST_FLAKY_RNG_TESTS when running the test suite, until we work out the cause.

hw/misc: Add npcm7xx random number generator
The RNG module returns a byte of randomness when the Data Valid bit is set.
This implementation ignores the prescaler setting, and loads a new value into RNGD every time RNGCS is read while the RNG is enabled and random data is available.
A qtest featuring some simple randomness tests is included.
