non-root: enable non-root checkpoint/restore

This commit enables checkpointing and restoring of applications as
non-root.

First goal was to enable checkpoint and restore of the env00 and
pthread00 test case.

This uses the information from opts.unprivileged and opts.cap_eff to
skip certain code paths which do not work as non-root.
