The '@' prefix in bpftrace map keys is specific to bpftrace and can be
safely removed when processing results. This patch modifies the bpftrace
utility to strip the '@' from map keys before storing them in the result
dictionary, making the keys more consistent with Python conventions.

Make sense, tho, could you double check or ask Alastair if all outputs
are prefixed with @? Maybe there's some map type or other thingamajig
that doesn't have the prefix?

I have a quick chat with Alastair earlier today, and I understood that
all map symbols start with @.

CCing him.
