[PATCH 2/5] libsepol: set number of target names

[Christian Göttsche <cgzones@xxxxxxxxxxxxxx>]

Set the number of target names to 0 instead of leaving it uninitialized.
The number is always 0 since CIL does not support non-trivial not-self
neverallow rules yet.

Reported by Clang Analyzer:

    module_to_cil.c:1211:18: warning: The right operand of '<' is a garbage value [core.UndefinedBinaryOperatorResult]
     1211 |                         for (t = 0; t < num_tnames; t++) {
          |                                       ^ ~~~~~~~~~~
