mesa: Remove C++11 narrowing warnings
Add -Wno-narrowing to CXXFLAGS for gcc.
It is safe to add this flag even for versions of gcc that don't recognize
it. From the GCC Manual [1]: "[GCC] allows the use of new -Wno- options
with old compilers".
This removes warnings of the form
warning: narrowing conversion of X from 'int' to 'float' inside { } is
ill-formed in C++11 [-Wnarrowing]
in ff_fragment_shader.cpp and gen6_blorp.cpp of the form. When building
i965, I observed no other difference in the build output.
