aux/lib.sh: Add mkstemp and mkdtemp, and copy uuid over

The tests were relying on the unspecified and non-standartized
behaviour of "mktemp".  Now they use "mkstemp()", a shim sh function to
provide the expected behaviour, and an accompanying "mkdtemp()"
function is also defined.

To further decouple from specific implementations and OS-behaviours and
quirks, a aux/lib.sh file containing both those functions was added.
Its purpose is to also allow code under aux/ to not depend on specific
behaviour.

"mkdtemp()" had to be replicated in aux/ci/ci-build.sh, since it runs
outside the repository.
