groff: Fix reproducibility issue
groff chooses a default papersize depending on the value from /etc/papersize
and failing that, the search domain in /etc/resolv.conf based on the comment
in configure:
"""
If the top-level domain is two letters and it's not 'us' or 'ca'
then they probably use A4 paper.
"""
Oddly, my system sets to "a4" in /etc/papersize which means it defaults to
"letter" since its != "A4".
These defaults ripple through to cause the output of man-db to change depending
on which default value was selected.
To resolve this, set a default of "A4" since that covers the larger population
of the two default values.
