package/ccache: do not force colored diagnostics

Browse Source 
When GCC_COLORS is set, ccache passes '-fdiagnostics-color' to GCC but
this flag requires GCC v4.9 or later. Older versions complain about the
unrecognized command line option.

Using GCC_COLORS in the context of Buildroot is seldom useful, so we
just unexport GCC_COLORS altogether.
