tdf#122425: explicitly remove borders for newly created flys

After commit d398e9248c183cf988b6d985b342b0cbff93ea02, it's necessary
to make sure that each created floating object has proper default
border and spacing values (empty and 0), to not inherit frame style's
non-0 values unintentionally.

This fixes two places for objects in headers/footers.
