chore(gnovm): add missing packages to stdlibWhitelist (gnolang#1677)

## Description

While I was working the
[JSON](gnolang#1415), @harry-hov requested
to update the package list. After checking, I noticed that multiple
packages were absent from the list, so I include them.

However, I omitted the testing package, as it appeared to be managed
independently.
