[Buildroot] [PATCH 1/2] package/leafnode2: fix build without pod2man

[Bernd Kuhls]

Fixes a build error when pod2man is missing on the host:

  pod2man ./tools/lsmac.pl >lsmac.1 || { rm -f lsmac.1 ; false ; }
  /bin/sh: line 1: pod2man: command not found

Fixes:
https://autobuild.buildroot.net/results/999/9996e81429f90f4615755827ac182094d416c467/

Although the build error only occurs since 2026-03-05 it should be
backported to LTS branches because the last change to the buildroot
package dates back to 2024.
