mozjs: disable null pointer optimization with GCC >= 6
Mozjs fails to start on several architectures due broken build
optimizations when built with GCC >= 6.
Set -fno-tree-vrp -fno-strict-aliasing -fno-delete-null-pointer-checks
to both CFLAGS and CXXFLAGS as workaround (flags also used by Firefox
and Fedora).
