Summary: This patch implements fwrite, putc, putchar, and fputc on the GPU. These are very straightforward, the main difference for the GPU implementation is that we are currently ignoring `errno`. This patch also introduces a minimal smoke test for `putc` that is an exact copy of the `puts` test except we print the string char by char. This also modifies the `fopen` test to use `fwrite` to mirror its use of `fread` so that it is tested as well.
