Sun's Loadmodule Patch

Sun's loadmodule fix replaces the insecure call to system(3) with calls to
vfork(2) and execle(3) (apparently execle(3) is used in order to specify
a null environment).

This is effective measure to fix loadmodule, uname(2) is still the most
elegant fix which has been overlooked.

Cheers,

Neil
