Strict aliasing issue in vxWorks "intLib" stub

[jphickey]

Describe the bug
When compiling with strict aliasing mode (gcc w/ -O3 -fstrict-aliasing -Wstrict-aliasing=2), a warning gets triggered in vxworks-intLib-stubs.c as follows:

osal/src/unit-test-coverage/ut-stubs/src/vxworks-intLib-stubs.c: In function ‘OCS_INUM_TO_IVEC’:
osal/src/unit-test-coverage/ut-stubs/src/vxworks-intLib-stubs.c:60:61: error: dereferencing type-punned pointer might break strict-aliasing rules [-Werror=strict-aliasing]
   60 |         UT_GetDataBuffer(UT_KEY(OCS_INUM_TO_IVEC), (void **)&VecTbl, &VecTblSize, NULL);
      |                                                             ^~~~~~~
cc1: all warnings being treated as errors

To Reproduce
Build with new-ish gcc (10.3) w/ -O3 -fstrict-aliasing -Wstrict-aliasing=2 options and tests enabled (so stubs are built).

Expected behavior
Should be clean.

System observed on:
Ubuntu

Additional context
Could be argued that stubs should not be built with optimization+strict aliasing rules, but the fix is relatively easy to avoid this warning.
