vf_unsharp: set default chroma size value to 5x5
...
The previous default value 0x0 was not good, since it is not even
valid.

vf_unsharp: fix out-of-buffer read
...
In apply_unsharp(), when y is >= height, prevent out-of-buffer reading
from src, read from the last buffer line in src2 instead.
The check was implemented in the original unsharp libmpcodecs code and
lost in the port.
This also fixes output discrepancy between the two filters.
