test: Add some tests for setexpr
This command currently has no tests. Add some for basic assignment and the integer operations. Note that the default size for setexpr is ulong, which varies depending on the build machine. So for sandbox on a 64-bit host, this means that the default size is 64 bits. Signed-off-by: Simon Glass <sjg@chromium.org>
