add --sysroot option

--root is not sufficient to properly operate on a mounted guest system.
Using --root still uses the host system's configuration and there is no
way to correctly use the guest configuration without manually modifying
any Include directives.  --sysroot provides an easier way to operate on
a guest system by chrooting immediately after option parsing before
configuration parsing or performing any operations.  It is currently
limited to the root user, but that's enough for restoring a guest system
to a working state, which is the primary intended use case.
