ports/unix/check: Split depfiles for faster build

Browse Source 
Having just one depfile (.depend) means it has to be fully regenerated
on every change, and it can't be done in parallel.

After this change the rebuild time after touching a single test file has
gone from 5.0 to 0.9 seconds. (make -j12)

Build of tests from clean has gone from 8.1 to 5.5s.

We could go even further and have one depfile per c-file, but this felt
like a simple first step giving a nice improvement.
