Remove link_fix.sh from build system (ufs-community#41)

## DESCRIPTION OF CHANGES: 
Remove the script link_fix.sh from the build system since the fix directories this script creates under ufs-srweather-app are not needed [the ones that are needed (in NCO mode) are under regional_workflow, not under ufs-srweather-app].

## TESTS CONDUCTED: 
On Orion, built successfully without link_fix.sh.

## CONTRIBUTORS (optional): 
@JeffBeck-NOAA
