btrfs-progs: Add some simple end-to-end tests for btrfs-convert

These use the system's mke2fs, and don't require loop devices
or root privileges.

They don't pick up anything with the default flags right now,
but they do pick up some sanitizer issues when the tools are
compiled with any of -fsanitize={address,memory,thread}.
