Mapmap build process outputs binary in the wrong location on Linux. (run.sh can't find it).

[DavidHaitch]

Expected Behavior

The documented build process should create a binary called "mapmap" in ./src/mapmap since that's where run.sh looks for it.

Actual Behavior

The build process creates a binary named "mapmap" in the root of the repository.

Steps to Reproduce the Problem

1. Run ./scripts/build.sh
2. Run ./scripts/run.sh
