Vincent Petry d69243ee51 Fixed FTP and SMB to use rmdir() when deleting folders
Some storages need to use different calls for deleting files or folders,
usually unlink() and rmdir().

Fixes #4532 (SMB dir deletion)
Fixes #5941 (FTP dir deletion)

Note that the extra is_dir() should be fast because it's read from the
stat cache.
