cmDependsC: remove code duplication

This patch reduces a bit code duplication by changing the way how the
case that we already have valid dependencies for a file is handled.
Instead of having the code for writing the depend-files twice,
we now fill the existing dependencies into the same set and then
write it out once at the end of cmDependsC::WriteDependencies()
