gvpack: cast assignment of string literal to 'rhs'

This pre-emptively squashes an upcoming warning when converting this file to C++
which otherwise fails the CMake build:

  cmd/tools/gvpack.cpp:122:17: error: ISO C++11 does not allow conversion from
    string literal to 'char *' [-Werror,-Wwritable-strings]

Gitlab: #2154
