gdb: fix warnings in bsd-kvm.c

Building on OpenBSD, I get warnings like:

      CXX    bsd-kvm.o
    /home/simark/src/binutils-gdb/gdb/bsd-kvm.c:241:18: error: ISO C++11 does not allow conversion from string literal to 'char *' [-Werror,-Wwritable-strings]
      nl[0].n_name = "_dumppcb";
                     ^

Silence those by adding casts.
