Fix includes with relative paths

The function `load_include_configs` already changes the directory to the
one containing the parent config. Therefore, `load_include_config`
trying to assemble the "full" path leads to repetition of path segments,
making the `realpath` call fail with ENOENT.

Just calling `realpath` on the path itself from the directory with the
parent configuration is sufficient, so there is no point in passing
`parent_dir` to `load_include_config`.
