[kbd] [Lint][Bug report] src/openvt.c:386: 'pid' may be used uninitialized

Hi,

I've found this bug using a static analyzer (slightly improved GCC).

Consider variable `pid` in function main from src/openvt.c:

src/openvt.c:166:       int opt, pid, i;
src/openvt.c:303:       if (direct_exec || ((pid = fork()) == 0)) {
src/openvt.c:386:       if (pid < 0)
src/openvt.c:393:               waitpid(pid, &retval, 0);

If direct_exec is TRUE, then pid doesn't get initialized, but it is used
outside the conditional regardless of that.
