r-maptree: use metadata checks

The "Unlimited" license text is taken from the "Writing R
Extensions" manual[0], which states that

"The mandatory ‘License’ field in the DESCRIPTION file should
specify the license of the package in a standardized form.
[...] Individual specifications must be one of [...] The
string ‘Unlimited’, meaning that there are no restrictions on
distribution or use other than those imposed by relevant laws
(including copyright laws)."
