Crate underhill_dump

Underhill process for writing core dumps.

underhill_dump <pid>

This command writes a core dump of process pid to stdout.

This is done as a separate process instead of inside the diagnostics process for two reasons:

1. To allow us to dump the diagnostics process.
2. To ensure that waitpid() calls by the diagnostics process do not get tracing stop notifications.
