module: icp: rip out the Solaris loadable module architecture

Browse Source 
After progressively folding away null cases, it turns out there's
/literally/ nothing there, even if some things are part of the
Solaris SPARC DDI/DKI or the seventeen module types (some doubled for
32-bit userland), or the entire modctl syscall definition.
Nothing.

Initialisation is handled in illumos-crypto.c,
which calls all the initialisers directly
