Installs a single file from a package_dir to the the target_dir. Replaces any prefix_placeholder in the file with the prefix.

relative_path is the path of the file in the package_dir (and the target_dir).

Note that usually the target_prefix is equal to target_dir but it might differ. See crate::install::InstallOptions::target_prefix for more information.
