scripts/decodecode: Fixup trapping instruction marker

When dumping "Code: " sections from an oops, the trapping instruction
%rip points to can be a string copy

2b:* f3 a5 rep movsl %ds:(%rsi),%es:(%rdi)

and the line contain a bunch of ":". Current "cut" selects only the and
the second field output looks funnily overlaid this:

2b:* f3 a5 rep movsl %ds <-- trapping instruction:(%rsi),%es:(%rdi

Fix this by selecting the remaining fields too.
