package/libnss: fix build failure due to patch not applicable

Current 0001 patch has been committed into buildroot before being
upstreamed. Now that it's been upstreamed it changed a little, so this
makes patch 0002(based on upstream version of patch 0001) impossible to
apply causing build failure while applying patches. So let's update
patch 0001 with upstream one.

Fixes:
