libseccomp 2.5.1 will break unit tests on ppc

Bug description:
[impact]
when libseccomp is upgraded to 2.5.1 on all releases, the systemd
seccomp unit tests will start failing on ppc, as
RestrictAddressFamilies= will no longer work on that arch.
However, the systemd.exec man page has stated that
RestrictAddressFamiles= doesn't work on ppc since before bionic.
[test case]
check systemd autopkgtest on ppc, looking at the
test_restrict_access_familes unit test
[regression potential]
any regression would involve the use of RestrictAddressFamilies=,
either no longer restricting or incorrectly restricting address
familes.
[scope]
this is needed for b/f/g
this was fixed upstream by commit
d5923e38bc0e6cf9d7620ed5f1f8606fe7fe1168 which is included in 247, so
this is fixed in h already
This isn't needed in x, because it doesn't include upstream commit
469830d1426a91e0897c321fdc8ee428f0a750c1 which reworked the code to
switch from seccomp_rule_add to seccomp_rule_add_exact, so systemd
could handle lack of arch support itself, instead of allowing the 'not
exact' seccomp syscall to just ignore the call due to lack of arch
support.
[other info]
libseccomp will be updated to 2.5.1 in the near future so this is
needed before that update
