[PATCH] package: disable libseccomp for find

[Martin Hundebøll]

Distros where libseccomp is enabled for the find util segfaults in
do_package:

$ file -S /usr/bin/file
Usage: file [-bcCdEhikLlNnprsvzZ0] [--apple] [--extension] [--mime-encoding]
             [--mime-type] [-e <testname>] [-F <separator>]  [-f <namefile>]
             [-m <magicfiles>] [-P <parameter=value>] <file> ...
        file -C [-m <magicfiles>]
        file [--help]

Only the latest release of file supports -S.
