Revert "Use %%license, license needs to be in -libs as it's the only guaranteed installed package, Move to mozjs38, Other upstream fixes, Spec cleanups"
    
    This reverts commit 53c8f9ed7f37b92447aa691813c3ec5e036cdee3.
    
    The mozjs38 patch does not work at all,
    https://bugzilla.redhat.com/show_bug.cgi?id=1438086 :
    > Successfully changed to user polkitd
    > 20:58:16.881: <no filename>:0: can't open init.js: No such file or directory
    
    Hence, restoring to a working state.
