util/spd_tools: Rebuild utils when source changes

This adds source file dependencies to utilities so that they are rebuilt
when the source is changed. Previously, binaries were only built if they
did not already exist and never rebuilt to reflect source file changes.

BUG=none
TEST=verified binaries are rebuilt when source files are touched.
