sunxi-mali-mainline: add EULA license file

sunxi-mali-mainline package has not license file at the moment.

License file is a pdf EULA, but its name contains whitespaces. This
gives problems when passing filename to SUNXI_MALI_MAINLINE_LICENSE_FILES
since it expects a list of files.
Other attempts with \ or \\ to keep spaces were tried with no luck.
Add a define to POST_PATCH_HOOKS to change pdf filename from
'EULA for Mali 400MP _AW.pdf' to 'EULA_for_Mali_400MP_AW.pdf'.
Add EULA file to hash.
