Add seven more xfstests to the main regression test group for the client

[Steve French]

FYI - with the features added to the client now in 5.13-rc1, I have
added 7 more xfstests to the main regression testing group (test
targets include various servers: Samba, Windows, Azure), and also to
the narrower test groups.   I do still need to check that they work to
ksmbd (the kernel server) and update that ksmbd test group later.  See
