main: add -bsd-keywords

To support either producing or checking manifests that are compatible
with upstream FreeBSD mtree(8) keywords, this flag will only operate on
upstream keywords. Completely ignoring non-upstream keywords, though
printing out an INFO to stderr for information purposes.

Example:
```bash
INFO: ignoring "xattrs" as it is not an upstream keyword

/set type=file nlink=1 mode=0664 uid=1000 gid=100
. size=4096 type=dir mode=0755 nlink=2 time=1469556206.235575511

[...]
```
