This change improves the GTHREAD_ONCE_INIT initializer
exposed by gthr-vxworks.h to use a more standard syntax
for a zero-initialization, which fixes build failures
observed when activating libstdc++ builds for aarch64-vxworks.

Tested in accordance with the description in
https://gcc.gnu.org/ml/gcc-patches/2019-12/msg00911.html

Committing to mainline.
