test/py: test the shell if command
Migrate all most tests from command_ut.c into the Python test system. This allows the tests to be run against any U-Boot binary that supports the if command (i.e. where hush is enabled) without requiring that binary to be permanently bloated with the code from command_ut. Some tests in command_ut.c can only be executed from C code, since they test internal (more unit-level) features of various U-Boot APIs. The migrated tests can all operate directly from the U-Boot console. Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Simon Glass <sjg@chromium.org>
