fsl-eula-unpack: deploy Freescale EULA

Add the file which contains the Freescale EULA to variable
LIC_FILES_CHKSUM, so the EULA is deployed in the folder

    ${LICENSE_DIRECTORY}/${PN}/

for all recipes which use the bbclass fsl-eula-unpack.

Add a vardepsexclude to variable LIC_FILES_CHKSUM to share the sstate
cache across multiple build directories.  See commit
