Bug fixes

[mikeowens]

Three small fixes:

1. FreeBSD open() does not have S_IRUSR | S_IWUSR
2. The source pointer for memcpy() in linenoiseHistorySave() is incorrect. It should point to head of list.
3. linenoiseHistorySave() needs to check for NULL pointer (although this was a side effect of (2))
