rGcd730bef74f9: nanobsd: Use mtree -C to produce the metalog

Summary

Prefer an mtree -C output, which is guaranteed to be mtree-compatible.
Add "gname", "uname", and "tags" to the default keyword set, while
removing "size" and "time", the latter being set on kernel file entries
and taking precedence over makefs -T (when paired with -F).

As a side effect, this produces a cleaner file with sorted keywords.

Test Plan

# sh nanobsd.sh -U -n -c ~/nano.conf
...
# shasum /usr/obj/nanobsd.full/_.disk.image
<matching hash>  /usr/obj/nanobsd.full/_.disk.image
# sh nanobsd.sh -U -n -c ~/nano.conf
...
# shasum /usr/obj/nanobsd.full/_.disk.image
<matching hash>  /usr/obj/nanobsd.full/_.disk.image

569	Do you want -u on the sort?

569	I guess it does not hurt to have it. `mtree-dedup.awk` should take care of duplicates, furthermore `mtree -C` removes the duplicate entries. But I'll add it when committing, just in case. Thanks!
