The SPL header has a function for obtaining the phase in capital letters, e.g. 'SPL'. Add one for lower-case also, as used by sandbox. Use this to generalise the sandbox logic for determining the filename of the next sandbox executable. This can provide support for VPL. Signed-off-by: Simon Glass <sjg@chromium.org>
