Add samba/ppc64el to big_packages

The samba tests spawn a lxd container to test a member server joining an
active directory domain controller on the host. The "lxc launch" command
has been failing with this error on ppc64el:

Error: Failed instance creation: websocket: close 1006 (abnormal
closure): unexpected EOF

Log inspection shows that the oom killer was invoked on the unsquashfs
process:

2023-03-24T12:22:41.258642+00:00 autopkgtest kernel: [ 313.097173] Out

LGTM. If we spot this failure mode on another arch I think we can move samba to big_packages on all archs.
