[TRIVIAL] fix regex-typo in documentation example

To match names beginning with the letters "f" or "b" one can use
the regular expression "[fb].*" or "(f|b).*", but not "[f|b].*",
which would match strings beginning with "f", "|", or "b".

start: switch ids at last possible instance

When the "lxc.rootfs.path" property is not set and users request a container
copy we would segfault since strstr() would be called on a NULL pointer.

This is technically not necessary but it is a privilege sensitive operation.
Meaning if anyone wants to do something that requires privilege it should be
done before the id switch. So let's move the id switch immediately before the
exec so that it's called at the last possible moment.
