bug#38838: 'whatis' doesn't work

[Jakub Kądziołka]

The 'whatis' utility from man-db 2.9.0 doesn't work for me. This
includes both my user profile and 'guix environment's. 'apropos' works,
so the man database is present and working.

$ guix environment --pure --ad-hoc man-db man-pages
[env] $ apropos memcpy
memcpy (3)           - copy memory area
wmemcpy (3)          - copy an array of wide-characters
[env] $ whatis memcpy
memcpy: nothing appropriate.
