Andrii Nakryiko 0b20933d8c tools/bpftool: Strip away modifiers from global variables 
Reliably remove all the type modifiers from read-only (.rodata) global
variable definitions, including cases of inner field const modifiers and
arrays of const values.

Also modify one of selftests to ensure that const volatile struct doesn't
prevent user-space from modifying .rodata variable.

Fixes: 985ead416d ("bpftool: Add skeleton codegen command")
