Fixes nob for when you have this pattern:

#ifdef OPTIM
#define CFLAGS "-O2"
#else
#define CFLAGS ""
#endif
....
cmd_append(&cmd, COMPILER_C, "-c" , "file.c" , CFLAGS , INCLUDES , "-o", "myexec");

When OPTIM is not defined, then CFLAGS is "" and execvp fails.
also works with #define CFLAGS NULL

Also fixes nob_cmd_render.

accepts arguments with empty strings
for (size_t i = 0; i < cmd.count; ++i) {
const char *arg = cmd.items[i];
if (arg == NULL) break;
if( arg[0] == '\0' ) continue;

It would be a good idea to conform the style to what is around. The spaces after ( and before ).
Less work for Zozin.
