Include meterpreter bins, add Sandbox builds

This commit contains the binaries that are needed for Juan's sandbox
escape functionality (ie. the updated old libloader code). It also
contains rebuilt binaries for all meterpreter plugins.

I've also added command line build scripts for the sandbox escapes
and added that to the "exploits" build.
