man: don't skip default path which appears in config file
If the MANPATH environment variable isn't set a provisional default
path of /usr/man is placed in man_path_list. This is only used if a
configuration file doesn't contain an alternative path.
If a configuration file lists the default path first:
MANPATH /usr/man:/usr/share/man
add_MANPATH() sees that the default entry is already present and skips
it. As a result man_path_list only contains the second and subsequent
components of the configured MANPATH.
In such cases the path should not be skipped.
