cbfstool: Make add-stage support multiple ignore sections

For x86 eXecute-In-Place (XIP) .data section support, cbfstool need to
to skip relocation of the .data section symbols in addition to
.car.data section symbols.

To support this requirement, this patch makes the `-S` option take a
multiple section names separated by commas.

TEST=With `-S ".car.data .data"`, XIP pre-memory stages with
     a `.data` section do not have any of the `.car.data` or `.data`
     section symbols relocated.
