Ports: Update and fix imgcat

- Update imgcat to 2.5.1 to get rid of prebuilt object files that have
  accidentally been included in the previous release tarball.
- Add a missing dependency on `termcap`.
- Remove an unused include of `err.h`, which we do not support.
- Use actually working settings for installing the built files.
