sandbox: Support executables for more phases
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.
