CI: kernel: use ccache to speedup workflow
Use ccache to speedup kernel compilation. Ccache dir is cached across each build test. To refresh ccache directory we generate an hash of the kernel include files, that includes the kernel versions of every kernel supported and the kernel compile includes. Signed-off-by: Christian Marangi <ansuelsmth@gmail.com> (cherry picked from commit 137ba15e6ef31534a2002a02e69b774232f0b040)
