This commit adds MSF-side support for listing currently loaded drivers
on the machine that Meterpreter is running on. It doesn't add a UI-level
command at this point, as I didn't see the need for it. It is, however,
possible to enumerate drivers on the target using the client API.
Also, the capcom exploit is updated so that it no longer checks for the
existence of the capcom.sys file in a fixed location on disk. Instead,
it enumerates the currently loaded drivers using the new driver listing
function, and if found it checks to make sure the MD5 of the target file
is the same as the one that is expected. The has is used instead of file
version information because the capcom driver doesn't have any version
information in it.
