cri-getplatforms: Honour new MF_SIMULATE_PLATFORMS env var

This is to be expanded by the shell, using eval, so that it can refer
to $xenarch, $suite and $blessing.

No functional change if this variable is unset, or empty.  If it is
set to a single space, cri-getplatforms produces no output (as it does
anyway in standalone mode).
