run-command: explicitly cast away constness when assigning to void

We do this:

  char *equals = strchr(*e, '=');

which implicitly removes the constness from "*e" and cause the compiler
to complain. We never write to "equals", but later assign it to a
string_list util field, which is defined as non-const "void *".

We have to cast somewhere, but doing so at the assignment to util is the
least-bad place, since that is the source of the confusion. Sadly we are
still open to accidentally writing to the string via the util pointer,
but that is the cost of using void pointers, which lose all type
information.
