[PATCH] bootgraph: fix for use with dot symbols

We have two symbols for each function, foo points to the function
descriptor, and .foo points to the instruction text. If we were to strip
the '.' when we print symbols then it would become harder to diagnose
some failures (eg branching to the function descriptor instead of the
instruction text).
