Add core filename to output of fusesoc core show.

This commit updates the output of `fusesoc core show` to add the
filename of the core file itself. This change is required for tools such
as the filelist Edalize backend as discussed in
olofk/edalize#25.

The output of `fusesoc core show` now looks like:

CORE INFO
Name:        vee:el:en:vee
Description: Top bombing
Core root:   /root/path/to/core/file
Core file:   basename.core
