Negate overlapping args with -o flag

Fixes: red-hat-storage#137

Right now if someone runs must-gather in odf mode
by using `-o` or `--odf` flag and also issues one
of `-c`, `-cl`, `-ns` or `-cs`, these scripts will
be executed twice, adding to the collection time and
creating redundant collection.

Essentially, this patch prevents execution of any of the
sub-scripts that are already called by `-o` flag.
