Subject: [PATCH] test/integration: Use realpath for paths and validate env
 vars in `rebase_patches`

A trailing slash in $SRCDIR breaks the backup `cp` command by
placing the ".orig" copy inside $SRCDIR instead of alongside it.
This causes the subsequent diff to fail. Fix this by using `realpath`
to canonicalize $SRCDIR. Additionally, add checks for required $SRCDIR,
$ID, and $VERSION_ID env vars.
