[PATCH 1/2] libsepol/cil: Update symtab nprim field when adding or removing datums

[James Carter <jwcart2@xxxxxxxxx>]

This field is suppose to be used to track the number of primary names in
the symtab. It was not being updated or used.

Increment the nprim field when a new datum is added to the symtab and
decrement the field when a datum is removed.
