py/getopt: allow --option arguments to contain '='

smb.conf lines can have = on the right hand side. For example, in
st/ad_dc/etc/smb.conf we have 3 examples, including:

 gpo update command = python3 source4/scripting/bin/samba-gpupdate [...] --target=Computer

If we tried to provide the same line via --option, it would split on
both '=', and the set value would end at '--target'.
