[NSKIP028] locale.getencoding() not implemented on Nanvix

Skip message

NSKIP028: locale.getencoding() not implemented on Nanvix

Root cause

Nanvix has no locale subsystem. locale.getencoding() raises or returns
None depending on call context. Tests that use getencoding() to pick
a fallback codec for filesystem paths are skipped.

Finding the footprint

rg -n 'NSKIP028'
