handle correctly symlinks in parent directories

Commit b9e2809fce57 introduced support for symlinks when specified in
the config file for one of the binaries, but it breaks if there is a
symlink in one of the parent directories.

This patch fixes the behavior by doing the following:

- get the absolute "real" path of the target file using realpath, not
  resolving symlinks for the parameter path (parents still get resolved)
- get the absolute "real" path of the current directory using realpath

This is necessary so that the two paths match in terms of symlinks
resolution.

- strip the base directory from the absolute path.

The result is the target file with a path relative to the current
directory without symlink resolution, but correctly handling the case
where symlinks are presents in the parent directories.
