[Qemu-devel] [PATCH V3] vl.c && linux-user/main.c : removed **envp from main() arguments

[Yoni Bettan]

it was added on 2008 902b3d5c39 when introduced cache-utils.[ch]

since then cache-utils.[ch] were removed but **envp was left
behind.

By the way "to be portable it is best to write main to take two
arguments, and use the value of environ" according to
https://www.gnu.org/software/libc/manual/html_node/Program-\
      Arguments.html#Program-Arguments

V2 -> V3:
    
    since ui/cocoa.c rename main() is using qemu_main() ,because it uses it 
    inside its main() function, the function qemu_main() can't be removed
  

V1 -> V2:

    removed the ui/cocoa.c renaming of main() function since i thought that we 
    no longer need qemu_main()
