[Mesa-dev] [PATCH] st/mesa: check for dummy programs in destroy_program_variants()

When we destroy an ARB vp/fp whose ID was gen'd but not otherwise used we
get a pointer to the dummy/placeholder program. We can't destroy that one
so just skip it. This only failed during context tear-down because
glDeleteProgramsARB() was already aware of dummy programs.
Fixes https://bugs.freedesktop.org/show_bug.cgi?id=38086
Note: This is a candidate for the stable branches.
