Fix bugs and regressions in the pledge command

Browse source 
This change gets the pledge (formerly pledge.com) command back in tip
top shape for a 3.0.1 cosmos release. It now runs on all platforms, even
though it's mostly a no-op on ones that lack the kernel security stuff.
The binary footprint is now smaller, since it no longer needs to link
malloc. It's also now able to be built as a fat binary.
