Those errors are the result in the name change for certain primitives in
the LuaTeX engine in 0.95 (TeXLive 2016). While most packages were
updated to reflect the changes, I don't think the booklet package was.
Fortunately the people at LuaTeX provide the luatex85 package which
defines the obsolete names in terms of their current ones. Simply add
`\usepackage{luatex85}` to the list of packages being loaded at the top
of the file and it should work just fine.
