Removed unveil call.
Removed unveil call.

As Bryan Steele correctly highlighted, the call to unveil actually
has no effect here for two reasons:

- calling unveil without a path like I did doesn't activate it
- going straight to a pledge of stdio disables file path accesses anyway

Therefore I have dropped unveil. Less code is better code.
