nshlib: Change ELF priority and stack size based on builtin list

Browse Source 
When an application is used as a loadable ELF module, the priority and
stack size of the application task is always fixed at the default values.

This commit changes to get the priority and stack size of the application
from the bulitin list. If it is not on the list, it still works as before.
