fpga: tools: Add contents of directories for HDL source

For HLS builds, the output file names aren't known in advance. This
makes it difficult to write the Makefile to pull in the files and pass
them to the build tools. This change allows you to add a directory as
your HDL source so that all files in the directory will be pulled in by
the build process.
