Don't try to truncate anything except for symlinks, directories, and
regular files.
ftruncate and truncate that go through FFS/EXT2FS/MFS will now return
EINVAL when done on devices.
Bug introduced when VOP_TRUNCATE was removed, thus removing spec_truncate.
Thanks to millert@ for tracking this one down.
