[build] Disable ccache for embedded.o
Embedded image support uses .incbin in inline assembly to include binary files. The file dependency is not spotted by ccache when deciding whether or not to rebuild embedded.o. This results in builds that contain an outdated version of the embedded image when ccache is used.
