Rename sources with overly verbose names.

Six source files contained "macports_legacy_" prefixes in their filenames, which is redundant and overly verbose. This removes those prefixes. No Makefile adjustment is needed, since it relies on wildcards. TESTED: Build succeeds and tests pass.

Rename sources with overly verbose names.
