[Samba] move from netatalk to samba + vfsfruit

[Reindl Harald]

since "ea = samba" was only added to very recent netatalk versions and
so don't apply to files with a history of many years what is the way to
go get rid of netatalk these days?

is there still no tool to read/write the existing netatalk appladouble
extended attributes which are *not* compatible with samba and write them
back in the new format?

afp.conf:
appledouble = ea
ea = samba

smb.conf:
vfs objects = catia fruit streams_xattr
ea support = yes
