Enable colored warnings in ninja's output
Summary:
Colored compiler warnings in ninja output only work with the
`-fdiagnostics-color=always` flag.
See https://github.com/ninja-build/ninja/issues/814 for a rationale.
This commit adds such flag in ecm for gcc >= 4.9 and clang >= 3.5,
and only if the CMAKE_GENERATOR is Ninja.
Test Plan: ninja+gcc and ninja+clang now show nice colored compiler warnings.
