[patch] Fix the plugin search in some file systems

[Rafael Espindola]

Hi,

Török reported that not all file systems support the d_type field in
"struct dirent". Reiserfs for example always returns DT_UNKNOWN.

The attached patch adds a stat if d_type is DT_UNKNOWN or DT_LNK. This
fixes the plugin search on file systems that don't support d_type and
also avoids getting confused with symbolic links to directories.

        * plugin.c (load_plugin): Don't skip entries with d_type == DT_UNKNOWN.
	Call stat on DT_UNKNOWN and DT_LNK entries.

Cheers,
