`man -H` doesn't use absolute path to groff

when running `man -H curl`, I get the following output:

```

man: command exited with status 255: (cd /tmp/hmanCnZGIK && /gnu/store/l9j6dsfs2i4spfkia492wnighplvhb1c-man-db-2.9.0/libexec/man-db/zsoelim) | (cd /tmp/hmanCnZGIK && /gnu/store/l9j6dsfs2i4spfkia492wnighplvhb1c-man-db-2.9.0/libexec/man-db/manconv -f UTF-8:ISO-8859-1 -t UTF-8//IGNORE) | (cd /tmp/hmanCnZGIK && /gnu/store/5sd2yanrfv9pq8mvnf4c6pga11r6x7qh-groff-minimal-1.22.4/bin/preconv -e UTF-8) | (cd /tmp/hmanCnZGIK && /gnu/store/5sd2yanrfv9pq8mvnf4c6pga11r6x7qh-groff-minimal-1.22.4/bin/tbl) | (cd /tmp/hmanCnZGIK && groff -mandoc -Thtml)

```

When I go into a guix environment containing groff however, it works.

Looking at the command `man -H` tries to use, it needs an absolute path

to groff.

I looked into this but it turns out that our man-db package is carefully

crafted not to refer to the full groff package to reduce its closure

size by more than half.

I think you'll have to live with installing groff manually to get the

HTML feature, or alter the man-db definition to your particular needs.

If this issue comes back often, we could revisit this choice and use the

full groff, which would mean adding about 50 MiB to the closure of the

bare-bones.tmpl system.

Closing,

Thanks for the report!
