conf: abort when include directive fails

When parsing the include directive, call glob() with the GLOB_ERR and
GLOB_NOMAGIC flags, and abort with an error message when matching of the
pattern failed with other error than GLOB_NOMATCH.

This restores the original behavior of the directive when it didn't
allow patterns, but it will still not fail with patterns not matching
any files in an existing directory.
